1ch DC/DC Converter IC with

PFM/PWM Synchronous Rectification

Description

MB39A135 is 1ch step-down DC/DC converter IC of the current mode N-ch/N-ch synchronous rectification method.

It contains the enhanced protection features, and supports the ceramic capacitor. MB39A135 realizes rapid response, high efficiency,

and low ripple voltage, and its high-frequency operation enables the miniaturization of inductor and I/O capacitors.

Features

■ High efficiency

■ For frequency setting by external resistor

■ Error Amp threshold voltage

: 100 kHz to 1 MHz

: 0.7 V 1.0 %

: 0.7 V

■ Minimum output voltage value

■ Wide range of power-supply voltage

: 4.5 V to 25 V

■ PFM/PWM auto switching mode and fixed PWM mode selectable

■ With built-in over voltage protection function

■ With built-in under voltage protection function

■ With built-in over current protection function

■ With built-in over-temperature protection function

■ With built-in soft start/stop circuit without load dependence

■ With built-in synchronous rectification type output steps for N-ch MOS FET

■ Standby current

■ Small package

: 0 μA (Typ)

: TSSOP-16

Applications

■ Digital TV

■ Photocopiers

■ Surveillance cameras

■ Set-top boxes (STB)

■ DVD players, DVD recorders

■ Projectors

■ IP phones

■ Vending machines

■ Consoles and other non-portable devices
