PAM2306D

Dual High-Efficiency PWM Step-Down DC-DC Coverter

Features

General Description

The PAM2306D is a dual step-down current-

n Efficiency up to 96%

mode, DC-DC converter. At heavy load, the

constant-fr equency PWM control performs

excellent stability and transient response. To

ensure the longest battery life in portable

applications, the PAM2306D provides a power-

saving Pulse-Skipping Modulation (PSM) mode to

reduce quiescent current under light load

operation.

n Only 40µA (Typ. per Channel) Quiescent

Current

n Output Current: Up to 1A per Channel

n Internal Synchronous Rectifier

n 1.5MHz Switching Frequency

n Soft Start

n Under-Voltage Lockout

n Short Circuit Protection

n Thermal Shutdown

n Small 12L WDFN3x3 Package

n Pb-Free Package and RoHS Compliant

The PAM2306D 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

dual output voltages are available for adjustment.

All versions employ internal power switch and

synchronous rectifier for 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

0.1μA. Other key features include under-voltage

lockout to prevent deep battery discharge.
