BP5293-XX Datasheet, PDF (1/19 Pages) Rohm – Over current protection

Smart Regulator Series
7 to 26V Input, 1.0A, Fixed Output Voltage
3 terminals DC/DC Regulator
BP5293-xx Series
●General Description
The BP5293-xx series is one packaged 3terminals Buck
type DC/DC Converter built-in all parts of DC/DC
converter.
High efficiency compared with 3 terminals regulator, and
not necessary to heat sink. It’s able to rearrange without
redesign PCB, because of pin compatible. The built in
input/output capacitors and coil is contribute to compact
design.
Supplied DC7V~26V output fixed voltage which is 1.8V,
3.3V, 5.0V, 12.0V line up. The output max current is 1A.
High efficiency at light load with a SLLMTM. It is most
suitable for use in the equipment to reduce the standby
power is required.
