Atmel Upgrades 4 Linear Regulator PMU Single Chip to 5V Input Supply

Rousset, France (ots/PRNewswire) -

- AT73C237 Integrates 4 Linear Regulators in a 3mm x 3mm QFN
Package

Atmel(R) Corporation (Nasdaq: ATML) announced today the release
of its AT73C237 Power Management Unit (PMU) compatible with a 5V
input supply and generating four regulated output voltages, with
programmable output voltage selection and output current up to 70mA.

The AT73C237 has a similar architecture to the established
AT73C239 PMU, but supports a 5V supply. It integrates four Linear Low
Drop Out (LDO) Regulators, three of which provide the high-accuracy
supply (programmable from 1.2V to 2.75V) required by RF and analog
devices, and one 1.8V regulator for backup battery/capacitor
recharging. It integrates a Two Wire Interface (TWI) to allow a
microcontroller to program the variable LDO output voltages and
manage the enable of each LDO.

"A number of customers have appreciated using the AT73C239 and
many of them have requested a direct 5V input. The AT73C237 was
designed to answer this requirement," commented Michele Casetta,
Marketing Manager for Atmel's Power Management And Analog Companions
(PMAAC) Product Line.

"A 3mm x 3mm QFN package integrating a four-channel power supply
is a major differentiator in the market and today customers can
connect the application supply (Li-Ion battery, AC/DC input, USB
port, etc.) directly to the AT73C237, thereby increasing the level of
analog integration, and minimizing the BOM cost and product size. The
AT73C237 is a universal PMU. Thanks to its extremely small package
and high integration, the AT73C237 can be used in a large number of
applications from portable devices to PC peripheral boards, from
wireless chipset supply (GPS, Bluetooth(R), etc.) to Ethernet powered
devices," concluded Michele Casetta.

Pricing and Availability

Atmel offers the AT73C237 in a 3 x 3 mm, 16-pin QFN package
priced at US$0.65 in quantities of 100K units. It is available now
mounted on a reference design board or as engineering samples.
