BP8708D - Integrated Flyback Switcher

Download the BP8708D datasheet PDF. This datasheet also covers the BP8705D variant, as both devices belong to the same integrated flyback switcher family and are provided as variant models within a single manufacturer datasheet.

General Description

The BP870X family is a series of highly integrated current mode PWM switcher ICs with high performance, low standby consumption suitable for designing flyback converters up to 25 W.

The BP870X integrates a 650 V power MOSFET and a high-voltage current source which eliminates the startup resistors.

Key Features

  • comprehensive protections, including cycle-by-cycle current limit, VCC over voltage protection and under voltage lock out, overload protection (BP870XD) or constant power output (BP870XBD), and over temperature protection. The BP870X is available in SOP-8 package. SOP-8 package Typical.

BP870XD/BP870XBD Integrated Flyback Switcher IC Description The BP870X family is a series of highly integrated current mode PWM switcher ICs with high performance, low standby consumption suitable for designing flyback converters up to 25 W. The BP870X integrates a 650 V power MOSFET 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 minimize the standby power. Frequency modulation and intelligent driving circuit are built in, which helps to achieve excellent EMI performance.
