DC/DC Converter+Reset
BH6557FV
Description
The BH6557FV is a variable output DC/DC converter
IC with reset. The DC/DC converter output voltage
value and reset voltage value can be adjusted by
external resistance.
Dimension
(Units : mm)
Features
1) Synchronous rectification enables high efficiency
2) Built-in charge pump circuits for operating output power MOS
3) Built-in variable reset circuit
4) Built-in power MOS Tr requires fewer external components
5) Mute circuit built-in
6) Built-in thermal shut down circuit
7) SSOP-B16 package has a smaller board footprint
