  1. PMP4440: 1W Isolated DC-DC Module Power _China Power Design Service • Features • Isolated interface FlybuckTM power supply with single channel output; • High efficiency of >86% at full load; • Good line and load regulation; • Low output ripple voltage; • Low cost, minimized component numbers; • Small PCB size, 19.8mm*9mm*5.8mm , 2 layer design • Pin to pin compatible with industry standard SIP modules , such as Mornsun power module ‘B0505LS-1WR2’ • Better performance than ‘B2405LS-1WR2’ • Applications • PLC, metering etc. Industrial • Telecom • Aux power

  2. PMP4440 Schematic

  3. Solution comparison with Mornsun module Line Regulation* : Test condition in Mornsun , the deviation of input voltage is only 1% But in TI that extended to 10% • Advantage • Higher efficiency • Better line and load regulation; • 100kHz to 2MHz operation frequency can be synchronized • ---Eliminating beat noise and Avoiding a sensitive frequency band • Adjustable Soft Start • ---Some modules will have a high inrush current • Full Features • --- Adjustable UVLO, Adjustable SS, Fault Indicator, EN, OCP, OTP • All Designs are Pin-to-Pin compatible, no need for PCB re-layout • Lower cost
