Description

The PMP21065 Reference design operates off a typical 12V DC input to produce several common rails seen in set top boxes today. The key objectives of the design are to be low-cost, small in size and low stand-by power with high efficiency to help customers meet compliance to new regulatory guidelines on STB power consumption.

Features
  • 10-14V input range, 12V typical
  • Multiple DC-DC output rails to meet typical STB requirements
  • Cost optimized design
  • Complete test report and design support collateral, including thermal performance
  • 1oz, 2-layer board measuring 4in x 2inaaaaaaaaaaaaaaa
