meanwhile new product keeps coming

Edinburgh, UK, 28 September 2010 - Wolfson Microelectronics plc has today announced the introduction of the highly innovative WM8325 power management subsystem, the world's highest current monolithic power management IC (PMIC), which delivers a cost-effective, flexible solution for portable multimedia applications including smartbooks, tablets, e-books, media players and smartphones.

The WM8325 features four programmable DC-DC converters, including one which is capable of delivering up to 2.5A; and eleven LDO regulators, four of which are low-noise for supplying sensitive analogue subsystems. Its optimised QFN package is designed to improve thermal performance and reduce parasitic components, enabling low cost four-layer printed circuit board (PCB) manufacturing. The package allows large PCB tracks for all high current paths, which improves transient performance. All this in conjunction with its low thermal resistance (24oC/W); its lower electrical resistance; and improved DC-DC technology ensures that the WM8325 delivers greater than 5% improvement in efficiency (at 1A) when compared with previous generations of PMIC DC-DC converters.

Also incorporated into the WM8325 is an on-chip regulator, which provides power for 'always-on' PMIC functions such as register map and the real-time clock, as well as offering autonomous backup battery switchover. A 12-bit auxiliary ADC also supports a wide range of applications for both internal and external analogue sampling, such as voltage detection and temperature measurement. Its one-time programmable (OTP) non-volatile memory delivers a highly flexible solution which also helps reduce time-to-market.

Its crystal oscillator and internal RC oscillator both generate all clock signals for autonomous system start-up and processor clocking, while a secure real-time clock (SRTC) and alarm function is included, capable of waking up the system from low-power modes. To maximise battery life, highly-granular power management enables each function in the WM8325 subsystem to be independently powered down through a control interface or alternatively through register and OTP-configurable GPIOs.

Jess Brown, Wolfson's Product Line Manager for Power Management, said: "We are delighted to introduce the world's highest current monolithic PMIC to the market. The WM8325 delivers world-leading power management, which simplifies design effort and saves cost whilst reducing time-to-market, making it ideal for next generation multimedia processors."

Nice recovery from the lows in SOL.N, currently above $12.50

Well, rumour as it is, its had an impact - WLF up whilst the current supplier, Cirrus Logic, down in the US (CRUS). If true, well, for long term holders here we go again.

[keybored] 30/9/2010 16:05

well that would have a huge positive impact if substantiated. Particularly on top of what is already a good turnaround

i think that the following article might go some way to explaining the sudden rise. I just hope it is true (from appleinsider.com):

A report out of the Far East early Thursday claims that Apple has decided on its lineup of component suppliers for the fifth-generation iPhone and second-generation iPad -- both of which will reportedly obtain baseband chips from CDMA inventor Qualcomm.

Rumors that Apple would dump Infineon chipsets in future versions of the iPhone began nearly a year ago when it was reported that Apple and Qualcomm met to discuss "future cooperation." Those sentiments were echoed once again, this time just three weeks ago when the Commercial Times pointed at Qualcomm-based iPhone 5.

blahblah.......

Meanwhile, that same report also claims knowledge of over a half-dozen other iPhone 5 and iPad 2 component suppliers -- many of which have remained the same. They include: CPU from Samsung, Wi-Fi chip from Marvell, Flash memory from Intel, touch screen controller by Broadcom,audio chip from Wolfson, video display interface chip from National Semiconductor/Infineon, Bluetooth from CSR and power management from TI.

volume huge today for WLF

[boadicea] 30/9/2010 14:09

Today's rise - over 12% - is in the region of requiring company comment - "Know no reason" or whatever.

[boadicea] 30/9/2010 12:53

Employee Trust buys, Artemis sells and the price is up 8%????

I don't think the share price is responding to either of these.
No doubt we shall find out what has leaked in due course.

I sold about half my holding, mostly in May, which doesn't now look too clever - but at least what I still hold are in for nothing when I add up all the deals over recent years.

[fenners66] 30/9/2010 10:26

So why the sudden rise today?

[xamf] 30/9/2010 10:25

Congratulations to all WLF longs.

[keybored] 29/9/2010 23:34

Wish I had followed the Bulldog signal myself.... hey ho

[pjw956] 29/9/2010 18:39

couple of large trades - delayed buys at 238 I guess

[pjw956] 26/9/2010 16:35

looking at the O trades - only a handful - most were already in

[keybored] 25/9/2010 21:35

Who followed the buy recommend ?

[keybored] 21/9/2010 17:59

WLF buy confirmed on British bulls today

[keybored] 19/9/2010 19:09

I think if q3 sees the growth and return to profit then the story the CEO has been telling for the last few Qtrs gains total cerdibility and could see £3 ish

[pjw956] 19/9/2010 10:16

yes - it was the closing auction that did the damage - and yes at these levels is a buying op - next target 250

[keybored] 17/9/2010 18:42

sort of talking to myself here... better not start replying to my own comments

[keybored] 17/9/2010 17:29

Actually just noticed the post bell sell did the damage

[keybored] 16/9/2010 11:11

could be a buying opportunity

[pjw956] 15/9/2010 16:46

many auto sells during the day - looking to push share price down for better entry point - long way up on not a lot of volume or news - so some taking profits - tomorrow another day - as they say...

[keybored] 15/9/2010 16:30

strange how the sells turned to buys in the last 5 mins and auction.

[pjw956] 15/9/2010 15:12

no buyers today ?
