ZSPM4013 High Efficiency 3 Amp DC-DC Buck Converter IC

The ZSPM4013 is a DC/DC synchronous switching regulator with fully integrated power switches, internal compensation, and full fault protection. The switching frequency of 1 MHz enables the use of small filter components, resulting in reduced board space and reduced BOM costs.

The ZSPM4013 utilizes current mode feedback in normal regulation PWM mode. When the regulator is disabled (EN is low), the device draws less than 10 uA quiescent current.

A wide range of protection circuitry is included: input supply under-voltage lockout, output voltage soft start, current limit, and thermal shutdown.

Supervisory reporting through the power good open drain output interfaces to other components in the system.
