Overview
MB39A112 3-ch DC/DC Converter IC The MB39A112 is a 3-channel DC/DC converter IC using pulse width modulation (PWM) , and the MB39A112 is suitable for downconversion.
3-channel is built in TSSOP-20P package.
Each channel can be controlled and soft-start.
The MB39A112 contains a constant voltage bias circuit for output block, capable of implementing an efficient high-frequency DC/DC converter.
It is ideal for built-in power supply such as ADSL modems.
Features ■ Supports for down-conversion (CH1 to CH3) ■ Power supply voltage range : 7 V to 25 V ■ Error amplifier threshold voltage : 1.
00 V ± 1% (CH1) : 1.
23 V ± 1% (CH2, CH3) ■ Oscillation frequency range : 250 kHz to 2.
6 MHz ■ Built-in soft-start circuit independent of loads ■ Built-in timer-latch short-circuit protection circuit ■ Built-in totem-pole type output for P-channel MOS FET devices ■ Built-in constant voltage (VCCO - 5 V) bias circuit for output block Package 20-pin plastic TSSOP (FPT-20P-M06) Cypress Semicond...
