Dual Channel, Step-Down

Converter/Linear Regulator

General Description

The AAT2505 is a member of AnalogicTech's Total

Power Management IC鈩?(TPMIC鈩? product fam-

ily. It is a low dropout (LDO) linear regulator and a

step-down converter with an input voltage range of

2.7V to 5.5V, making it ideal for applications with

single cell lithium-ion / polymer batteries.

The LDO has an independent input pin and is capa-

ble of delivering up to 300mA of current. The linear

regulator has been designed for high-speed turn-on

and turn-off performance, fast transient response,

and good power supply rejection ratio (PSRR).

Other features include low quiescent current, low

dropout voltage, and a Power-OK (POK) open drain

output signaling when V

OUT

is in regulation.

The 600mA step-down converter is designed to

operate with 1.4MHz of switching frequency, mini-

mizing external component size and cost while

maintaining a low 27碌A(chǔ) no load quiescent current.

Peak current mode control with internal compen-

sation provides a stable converter with a low equiv-

alent series resistance (ESR) ceramic output

capacitor for extremely low output ripple.

For maximum battery life with high voltage outputs,

the step-down converter duty cycle increases to

100%. The output voltage is either fixed or adjustable

with an integrated P- and N-channel MOSFET power

stage and 1.4MHz switching frequency.

The AAT2505 is available in a Pb-free, 12-pin

TDFN33 package and is rated over a temperature

range of -40擄C to +85擄C.
