LMZ12003 - 3A SIMPLE SWITCHER Power Module

General Description

Pin 1 2 3 4 5 6 Name Description VIN RON EN GND SS FB Supply input

Nominal operating range is 4.5V to 20V .

A small amount of internal capacitance is contained within the package assembly.

Additional external input capacitance is required between this pin and exposed pad.

Key Features

  • Integrated shielded inductor.
  • Simple PCB layout.
  • Flexible startup sequencing using external soft-start capacitor and precision enable UVLO and output short circuit 30109018 Thermal derating curve VIN = 12V VOUT = 5.0V.
  • Protection against inrush currents and faults such as input.
  • -40°C to 125°C junction temperature range.
  • Single exposed pad and standard pinout for easy mounting and manufacturing.
  • Fast transient response for FPGAs and ASICs.
  • Low output v.
