The PMA series P3BU-xxxxELF is a family of cost effective 0.5 W single
output DC/DC converters. These converters are in an ultra miniature DIP8
case. Devices are encapsulated. High performance features: 1000VDC
input/output isolation, high efficiency operation, output voltage accuracy of
±3% maximum, input range of ±10% tolerance and low output ripple and
noise.
All specifications typical at Ta=25° nominal input voltage and full load unless otherwise specified

App Notes:
¹ =
Measured Input reflected ripple current with a simulated source inductance of 12uH.
² =
Tested by minimal Vin and constant resistive load.
- Operation under no-load conditions will not damage these devices, but they will not observe the listed specifications.
- For reduce converter’s ripple & noise, it is recommended to add a 4.7µF~100µF capacitor in output end. For EMI performance
improvement, it is recommended to add a 12µH inductor and a 10µF~220µF capacitor in input end.
