Low Power Off-line Buck Supplies a Fixed Voltage 13V@120mA from Universal Line
Description
The PMP8550 reference design uses the UCC28880 low power: low cost: off-line buck converter with integrated 700V MOSFET to generate a non-isolated 13V/120mA output from a Universal AC line input. Thanks to its hysteretic mode: no loop compensation is needed reducing BOM count to 23 components producing a single sided: double layer board size of just 38mmx32mmx22mm which can be used in numerous industrial applications such as smart meters: home automation equipment and white goods.
Features
- High-side buck topology Regulated output voltage between 13V and 12.8V with minimum 10% load Reference design total quiescent current draw of 119uA at high line Excellent system performance under excessive currents: Along with current limit function: the controller’s inductor current runaway protection helps protect against under load short-circuit conditions to ensure design reliability. Thermal protection: Over-temperature protection with hysteretic re-start for safe operation
