ZSPM4012B

High Efficiency 2A Synchronous

Buck Converter

Datasheet

Brief Description

Benefits

The ZSPM4012B is

DC/DC synchronous

•

Increased battery life

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.

Minimal external component count

(3 capacitors, 1 inductor)

•

Inherent fault protection and reporting

Available Support

•

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.

Evaluation Kit

Documentation

Physical Characteristics

•

Junction operating temperature -40°C to 125°C

Packaged in a 16pin QFN (3x3mm)

The ZSPM4012B integrates a wide range of

protection circuitry, including input supply under-

voltage lockout, output voltage soft start, current

limit, V_OUTover-voltage, and thermal shutdown.

The ZSPM4012B includes supervisory reporting

through the PG (Power Good) open drain output to

interface other components in the system.
