Brief Description
The ZSPM4012 is a DC/DC synchronous switching
regulator with fully integrated power switches,
internal compensation, and full fault protection. The
switching frequency of 1MHz enables the use of
small filter components, resulting in reduced board
space and reduced BOM costs.
The ZSPM4012 utilizes current mode feedback in
normal regulation PWM mode. When the regulator
is disabled (EN is low), the device draws less than
10uA quiescent current.
The ZSPM4012 integrates a wide range of protection
circuitry,
lockout, output voltage soft start, current limit, and
thermal shutdown.
The ZSPM4012 includes supervisory reporting
through the PG (Power Good) open drain output to
interface other components in the system.
