Low Vin, Small Form Factor Flyback Reference Design for High Voltage Laser Flash Drive

PMP10712

Design files

Overview

PMP10712 is a 1.2W, small form factor, isolated flyback design that supports very low Vin of 3.3V-6V and is capable of delivering 10mA at 120V output. The design uses LM3481 Boost controller IC which works on current mode operation and can be synchronized to any frequency between 100KHz to 1 MHz.

This design was built on a 2 layer board and is a simple, low-BOM-count, and low-cost design providing an isolated output.

Features
  • Low Cost Flyback design for low Vin to  High voltage output
  • Ultra Low Footprint Area for LM3481 Actual Power Stage
  • 100-kHz to 1-MHz Adjustable Synchronizable Clock Frequency and limits the inrush current at start-up
  • IC capable of 3V to 40V in
