PAM2304

3MHz, 1A Step-Down DC-DC Converter

Features

General Description

The PAM2304 is a step-down current-mode, DC-

DC converter. At heavy load, the constant-

frequency PWM control performs excellent

stability and transient response. To ensure the

longest battery life in portable applications, the

n Efficiency up to 95%

n Only 40μA(TYP.) Quiescent Current

n Output Current: Up to 1A

n Internal Synchronous Rectifier

n 3MHz Switching Frequency

n Soft Start

PAM2304 provides

a power-saving Pulse-

Skipping Modulation (PSM) mode to reduce

quiescent current under light load operation to

save power.

n Under-Voltage Lockout

n Short Circuit Protection

n Thermal Shutdown

n Small TSOT23-5, TDFN22-8 and

TDFN22-6 Packages

n RoHS Pass and Green Package

The PAM2304 supports a range of input voltages

from 2.5V to 5.5V, allowing the use of a single

Li+/Li-polymer cell, multiple Alkaline/NiMH cell,

USB, and other standard power sources. The

output voltage is adjustable from 0.6V to the input

voltage. All versions employ internal power switch

and synchronous rectifierfor to minimize external

part count and realize high efficiency. During

shutdown, the input is disconnected from the

output and the shutdown current is less than 1 μA.

Other key features include under-voltage lockout

to prevent deep battery discharge.

Applications

n Smart Phone

n MID

n Portable Electronics

n Wireless Devices

n Cordless Phone

n Computer Peripherals

n Battery Powered Widgets

n Electronic Scales

n Digital Frame

The PAM2304 is available in TSOT23-5, TDFN22-

8 and TDFN22-6 packages.
