Small size, 8-PIN Package (SOIC or TSSOP)
Lead Free Available (RoHS Compliant)
The APW7037 series are designed to provide a low
cost synchronous Buck regulator for on-board DC to
DC converter applications. The APW7037 series to-
gether with dual N-channel MOSFETs such as
APM7313, provide a low cost solution for such
applications. Each device features an internal 200/
400kHz oscillator, Power-On-Reset (POR) for both VCC
and VC supplies, an external programmable soft-start
function as well as output under-voltage detection that
latches off the device when an output short is detected.
