FP6733

PWM Controlled, Step-up DC/DC

Converter in Tiny Package

Description

Features

The FP6733 is a high efficiency PWM DC/DC

step-up converter with internal compensated current

mode controller. The output voltage is set by using

 0.9V (Typ.) Low Start-up Input Voltage at 1mA

Load

 High Switching Frequency at 550kHz

two external resistors.

The 550kHz switching

 Provide Flexibility for Using Internal and External

Power Switches

frequency

minimizes the size of external

components. Both internal 1A switch and driver for

driving external power device (NMOS or NPN) are

provided.

 Automatic PFM Mode at Light Load

 Low Ripple and High Efficiency

 Excellent Line/Load Regulation

 Chip Enable Control Function

 Current Limit Protection

 Thermal Overload Protection

 Space Saving Packages: SOT-23-6 and

TSOT-23-6

The FP6733 starts up below 1V input voltage with

1mA load. Due to built-in automatic PWM/PFM

switch-over function, the FP6733 is able to get high

efficiency during both light and heavy load.

External transistor pin is available to accommodate

high output current applications.

Applications

 PDA

The FP6733 is available in SOT-23-6 and

TSOT-23-6 packages.

 MP3

 DSC

 RF Tag

 Wireless Equipment

 Portable Equipment
