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.
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%
-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)
