Description
MB39A123 is a 6-channel DC/DC converter IC using pulse width modulation (PWM) , and it is suitable for up conversion, down conversion, and up/down conversion.
Features
- Supports for step-down with synchronous rectification (ch.1).
- Supports for step-down and up/down Zeta conversion (ch.2 to
ch.4).
- Supports for step-up and up/down Sepic conversion (ch.5,
ch.6).
- Negative voltage output (Inverting amplifier) (ch.4).
- Low voltage start-up (ch.5, ch.6) : 1.7 V.
- Power supply voltage range : 2.5 V to 11 V.
- Reference voltage : 2.0 V 1%.
- Error amplifier reference voltage : 1.0 V 1% (ch.1) , 1.23 V ±
1% (ch.2 to ch.6).
