4-ch DC/DC Converter IC
MB39A102
â DESCRIPTION
The MB39A102 is a 4-channel DC/DC converter IC using pulse width modulation (PWM). This IC is ideal for up
conversion, down conversion, and up/down conversion.
4ch is built in TSSOP-30P/BCC-32P package. Each channel can be controlled, and soft-start.
This is an ideal power supply for high-performance portable devices such as digital still cameras.
â FEATURES
⢠Supports for down-conversion and up/down Zeta conversion (CH1 to CH3)
⢠Supports for up-conversion and up/down Sepic conversion (CH4)
⢠Power supply voltage range : 2.5 V to 11 V
