High Performance Non-isolated PFM converters--PN8048

一、General Description

The PN8048 consists of an integrated Pulse Frequency Modulator (PFM) controller and power MOSFET，specifically designed
for small power non-isolated switching power supply. PN8048 has internal high voltage start-up circuit and complete intelligent
protections including Over Load Protection (OLP), Under Voltage Lockout (UVLO) and Over Temperature Protection (OTP).

Excellent EMI performance could be achieved with Pulse Frequency Modulation.

二、Features
■ Internal 650V avalanche-rugged smart power VDMOSFET
■ Internal HV Start-up Circuit
■ Be optimized with 18V output non-isolated application
■ Semi enclosed steady output power 10.8W @230VAC, DIP-8
■ Frequency modulation for low EMI
■ Excellent constant voltage regulation and High efficiency
■ Excellent Protection Coverage:

三、Applications

Non isolated auxiliary power supply
