PMP20182, Ultra-wide Input Range (10.8V to 264V AC or DC) Bias Power Supply Reference Design. The PMP20182 can handle 10.8V to 264V, AC or DC input voltage range and generate 12V/55mA output. With the use of UCC2813 PWM controller (up to 100% duty cycle) and Buck-boost topology, this ultra-wide input range power supply is made possible. This design uses a depletion MOSFET for fast startup - less than 50mS startup time is achieved with 12VDC input. Dimension of this board is 20mm (W) x 60mm (L) x 10.5mm (H)
