BP87112 - Integrated Flyback Switcher

Description

The BP87112 is a current mode PWM switcher IC with high performance, high integration and low standby consumption.

The BP87112 integrates a 650 V MOS-bipolar composite power switch and a high-voltage current source which eliminates the startup resistors.

It supports CCM and DCM operations.

Features

  • comprehensive protections, including cycle-by-cycle current limit, output over voltage protection and under voltage protection, VCC over voltage protection and under voltage lock out, and over temperature protection. The BP87112 is available in ESOP-6 package. ESOP-6 package Typical.

BP87112 Integrated Flyback Switcher IC Description The BP87112 is a current mode PWM switcher IC with high performance, high integration and low standby consumption. The BP87112 integrates a 650 V MOS-bipolar composite power switch and a high-voltage current source which eliminates the startup resistors. It supports CCM and DCM operations. At full load, the IC operates in 65 kHz fixed frequency. When the load goes down, it operates in Green Mode while the oscillator frequency is controlled by the feedback voltage on the FB pin. At no load condition, the IC operates in burst mode to reduce the standby power. Frequency modulation and intelligent driving circuit are built in, which helps to achieve excellent EMI performance. Internal slope compensation improves the system stability.
