ZSPM4012B
Datasheet
Brief Description
The ZSPM4012B is a DC/DC synchronous
switching regulator with fully integrated power
switches, internal compensation, and full fault
protection. The 1MHz switching frequency enables
using small filter components, resulting in reduced
board space and reduced bill-of-materials costs.
The ZSPM4012B utilizes current mode feedback in
normal regulation pulse-width modulation (PWM)
mode. When the regulator is disabled (EN pin is
low), the ZSPM4012B draws less than 10µA quies-
cent current.
The ZSPM4012B integrates a wide range of
protection circuitry, including input supply under-
voltage lockout, output voltage soft start, current
limit, V
OUT
over-voltage, and thermal shutdown.
The ZSPM4012B includes supervisory reporting
through the PG (Power Good) open drain output to
interface other components in the system.
