Switching Regulator Controller

MB3782

■ DESCRIPTION

The FUJITSU MB3782 is a PWM-type switching regulator controller, designed with open-collector output for

connection to external drive transistors and coils, providing a selection of three types of output voltage: step-up,

step-down or inverting (inverting output is available on one circuit only).

The MB3782 features identical oscillator output waveforms to enable completely synchronous operation and

prevent the occurrence of low-frequency beat between channels.

Also, the MB3782 features low power dissipation (2.1 mA Typ) and a built-in standby mode (10 µA), making

possible the configuration of a wide variety of high-efficiency, stable power supplies, even with the use of battery

power. The MB3782 is an ideal power supply for high-performance portable devices such as video camcorders

and cameras.

■ FEATURES

• Wide voltage range (3.6 V to 18 V)

• Low power dissipation (operating mode: 2.1 mA (Typ), standby mode: 10 µA (Max)

• Wide range of oscillator frequencies, high-frequency capability (1 to 500 kHz)

• On-chip timer-latch type short detection circuit

• On-chip undervoltage lockout circuit

• On-chip 2.50 V reference voltage circuit (1.25 V output available at R^Tpin)

• Dead time adjustment over full duty cycle range

• On-chip standby mode (power on/off function)
