The LMZ12002EXT SIMPLE SWITCHER® power module is an easy-to-use step-down DC-DC solution capable of driving up to 2A load with exceptional power conversion efficiency, line and load regulation, and output accuracy. The LMZ12002EXT is available in an innovative package that enhances thermal performance and allows for hand or machine soldering.

The LMZ12002EXT can accept an input voltage rail between 4.5V and 20V and deliver an adjustable and highly accurate output voltage as low as 0.8V. The LMZ12002EXT only requires three external resistors and four external capacitors to complete the power solution. The LMZ12002EXT is a reliable and robust design with the following protection features: thermal shutdown, input under-voltage lockout, output over-voltage protection, short-circuit protection, output current limit, and allows startup into a pre-biased output. A single resistor adjusts the switching frequency up to 1 MHz.

Electrical Specifications

12W maximum total power output

Up to 2A output current

Input voltage range 4.5V to 20V

Output voltage range 0.8V to 6V

Efficiency up to 92%

Key Features

-55°C to 125°C junction temperature range

Integrated shielded inductor

Simple PCB layout

Flexible startup sequencing using external soft-start capacitor and precision enable

Protection against inrush currents and faults such as input UVLO and output short circuit

Single exposed pad and standard pinout for easy mounting and manufacturing

Fast transient response for FPGAs and ASICs

Low output voltage ripple

Pin-to-pin compatible family:

LMZ14203EXT/2EXT/1EXT (42V max 3A, 2A, 1A)

LMZ14203/2/1 (42V max 3A, 2A, 1A)

LMZ12003/2/1 (20V max 3A, 2A, 1A)

Fully Webench® Power Designer enabled
