Texas Instruments UCC28880 | Demoboard PMP8550

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

Remark: Schematic,BOM and Test results are added.

• 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
