LMZ10503 - Power Module

General Description

Pin Number 1 2 3 Name VIN EN SS Description Power supply input.

A low ESR input capacitance should be located as close as possible to the VIN pin and exposed pad (EP).

Active high enable input for the device.

Key Features

  • Integrated shielded inductor.
  • Flexible startup sequencing using external soft-start, tracking, and precision enable UVLO and output short-circuit Efficiency (VOUT = 3.3V).
  • Protection against in-rush currents and faults such as input.
  • -40°C to +125°C junction temperature operating range.
  • Single exposed pad and standard pinout for easy mounting and manufacturing.
  • Pin-to-pin compatible with LMZ10504 (4A/20W max) LMZ10505 (5A/25W max).
  • Fully enabled for WEBENC.
