DESCRIPTION

The MB3825A is a pulse width modulation (PWM) type 6-channel DC/DC converter IC with synchronous rectification (2-channels) designed for low voltage, high efficiency operation in high precision and high frequency applications, ideal for down conversion.

The MB3825A is an ideal device offering low power consumption, compact size and light weight for products such as self-contained camcorders and digital still cameras.

This product is covered by US Patent Number 6,147,477.

FEATURES

• Synchronous rectification (channels 1 and 4)

• High efficiency drive with power-on output enhanced by built-in speed-up circuit

• Wide range of operating power supply voltage : 2.5 V to 12 V

• Built-in high-precision reference voltage generator : 1.5 V ± 1

• Wide operating oscillator frequency range, high frequency capability : 50 kHz to 800 kHz

• Wide input voltage range (all channels) : 0 V to Vcc − 0.9 V

• Error amplifier output for soft-start (channels 1, 2, 4) (All channels may be set for same soft-start time regardless of duty factor setting.)
