Datasheet

AC/DC Converter

PWM Type DC/DC Converter IC

Built-in a Switching MOSFET

BM2P0161-Z BM2P0361-Z

General Description

Key Specification

◼ Operating Power Supply Voltage Range:

The PWM type DC/DC converter for AC/DC provides an

optimal system for all products that require an electrical

outlet.

VCC:

8.9 V to 26.0 V

730 V (Max)

DRAIN:

BM2P0161-Z and BM2P0361-Z support both isolated and

non-isolated devices, enabling simpler design of various

types of low power consumption electrical converters.

The built-in 730 V starter circuit contributes to low-power

consumption.

◼ Circuit Current (ON)1:

BM2P0161-Z: 0.90 mA (Typ)

BM2P0361-Z: 0.65 mA (Typ)

0.30 mA (Typ)

◼ Circuit Current (ON)2:

◼ Oscillation Frequency1:

65 kHz (Typ)

Power supply can be designed flexibly by connecting

current sensing resistor for the switching externally.

Current is restricted in each cycle and excellent

performance is demonstrated in bandwidth and transient

response since current mode control is utilized. The

switching frequency is 65 kHz. At light load, the switching

frequency is reduced and high efficiency is achieved. A

frequency hopping function that contributes to low EMI is

also included on chip.

◼ Operating Ambient Temperature: -40 °C to +105 °C

◼ MOSFET ON Resistance:

BM2P0161-Z: 1.0 Ω (Typ)

BM2P0361-Z: 3.0 Ω (Typ)

Package

W (Typ) x D (Typ) x H (Max)

9.27 mm x 6.35 mm x 8.63 mm

Pitch 2.54 mm

DIP7K

DIP7WF

9.35 mm x 6.35 mm x 8.10 mm

Pitch 2.54 mm

Design can be easily implemented because includes a

730 V switching MOSFET.

Feature

◼ PWM Current Mode Control

◼ Built-in Frequency Hopping Function

◼ Burst Operation When Load is Light

◼ Frequency Reduction Function

◼ Built-in 730 V Starter Circuit

◼ Built-in 730 V Switching MOSFET

◼ VCC Pin Under-Voltage Protection

◼ VCC Pin Over-Voltage Protection

◼ SOURCE Pin Short Protection

◼ SOURCE Pin Leading Edge Blanking Function

◼ Per-Cycle Over-Current Protection Circuit

◼ Over Current Protection AC Voltage Compensation

Circuit

Application

For AC Adapters, TV and Household Appliances (Vacuum

Cleaners, Humidifiers, Air Cleaners, Air Conditioners, IH

Cooking Heaters, Rice Cookers, etc.)

◼ Soft Start

◼ Secondary Over-Current Protection Circuit

Typical Application Circuit
