Datasheet

AC/DC Convertor IC

PWM type DC/DC converter IC

Integrated Switching MOSFET for non-Isolated type

BM2P159PF

General

The PWM type DC/DC converter BM2P159PF for

Basic Specification

Power Supply Voltage Operation Range:

AC/DC provides an optimum system for all products

that include an electrical outlet. It enables simpler

design of a high effective converter specializing in

non-isolated devices.

VCC: ： 12.40V to 15.33V

DRAIN:

to 650V

■Normal Operation Current

0.85mA (Typ.)

1.05mA(Typ.)

100kHz(Typ.)

- 40 ^oC to +105 ^oC

9.5Ω(Typ.)

This series has a built-in HV starter circuit that

tolerates 650V, and it contributes to low power

consumption. With a current detection resistor for

switching as internal device, it can be designed as

small power supply. Since current mode control is

utilized, current is restricted in each cycle and

excellent performance is demonstrated in bandwidth

and transient response. The switching frequency is

fixed to 100 kHz. A frequency hopping function is also

on chip, and it contributes to low EMI. In addition, a

built-in super junction MOSFET which tolerates 650V

makes the design easy.

■Burst Operation Current

Oscillation Frequency

Operation Temperature Range

MOSFET ON resistor:

Package

SOP8 5.00mm x 6.20mm x 1.71mm pitch 1.27mm

(Typ.) (Typ.) (Max.) (Typ.)

Features

 PWM frequency: 100kHz

 PWM current mode method

 Frequency hopping function

 Burst operation at light load

 Built-in 650V start circuit

 Built-in 650V switching MOSFET

 VCC pin under voltage protection

 VCC pin over voltage protection

 Over current limiter function per cycle

 Soft start function

Application

Households such as LED lights, air conditioners, and

cleaners, (etc.).

Application circuit
