LTM8031

• Product Introduction

LTM8031 ultra-low noise, EMC-compliant 36V, 1A DC/DC μModule regulator

Features Complete buck-type switch-mode power supply Wide input voltage range: 3.6V to 36V 1A output current Output voltage from 0.8V to 10V Switching frequency: 200kHz to 2.4MHz Meets EN55022 Class B specification requirements with margin reserved Current mode control Lead-free (e4) packaging with a gold liner coating and RoHS compliance Programmable soft start Compatible with LTM8032 pins Flat (9mm x 15mm x 2.82mm) surface-mount LGA package Description The LTM®8031 is an electromagnetically compatible (EMC) 36V, 1A DC/DC μModule® buck converter, specifically designed to meet EN55022 standard radiated emission requirements. Conducted emission requirements can be met by adding standard filter elements. The package includes a switch controller, power switch, inductor, filter, and all supporting components. LTM8031 Operates within an input voltage range of 3.6V to 36V, supporting an output voltage range of 0.8V to 10V and a switching frequency range from 200kHz to 2.4MHz (all set by a single resistor). Complete designs can be achieved simply by using large-capacity input and output filter capacitors. Thanks to the flat (height only 2.82mm) package, unused space at the bottom of the PC board can be utilized for high-density load point adjustment. LTM8031 Uses heat-resistant, compact (9mm x 15mm), flat (height only 2.82mm) molded resin pad mesh array (LGA) package, suitable for automated assembly using standard surface-mount equipment. LTM8031 Compliant with RoHS standards. Application Car battery regulation Portable product power supply Distributed power regulation Industrial power supply Wall transformer adjustment
