Overview

Topology	Buck Converter
Input voltage	6-24 V
Output 1	5 V / 2 A
IC revision	1.1

Description

The ZSPM4012 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 ZSPM4012 utilizes current mode feedback in normal regulation pulse-width modulation (PWM) mode. When the regulator is disabled (EN pin is low), the ZSPM4012 draws less than 10μA quiescentcurrent. The ZSPM4012 integrates a wide range of protection circuitry, including input supply undervoltage lockout, output voltage soft start, current limit, VOUT over-voltage, and thermal shutdown. The ZSPM4012 includes supervisory reporting through the PG (Power Good) open drain output to interface other components in the system.

Features

Output voltage options depending on ordercode
Fixed output voltages: 1.5V, 1.8V, 2.5V, 3.3V, or 5V with +/- 2% output tolerance
Adjustable output voltage range: 0.9V to 5V with +/- 1.5% reference
Wide input voltage range:6V to 24V
1MHz +/- 10% fixed switching frequency
2A continuous output current
High efficiency – up to 95%
Current mode PWM control with pulsefrequency modulation (PFM) mode for improved light load efficiency
Voltage supervisor for VOUT reported at the PG pin
Input supply under voltage lockout
Soft start for controlled startup with no overshoot
Full protection for over-current, overtemperature, and VOUT over-voltage
Less than 10μA in Disabled Mode
Low external component count

Typical applications

Printers
Portable products, including
Set-top boxes
Wireless access points, cable
DVD, LCD, LED supplies
