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


ROUSSET, France, June 24 /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.
