General Description

Key Specifications

◼ Power Supply Voltage Operation Range:

This series IC is a PWM type DC/DC converter for

AC/DC which provides an optimum system for various

electrical product. It supports both isolated and non-

isolated devices, enabling simpler design of various

types of low power consumption electrical converters.

This series also has a built-in

starter circuit that can withstand up to 730 V, which

contributes to low power consumption. Since current

mode control is utilized, current is restricted in each

cycle and excellent performance is demonstrated in

bandwidth and transient response. Switching frequency

is fixed at 65 kHz, 100 kHz or 130 kHz. At light load, the

switching frequency is reduced and high efficiency is

achieved. A frequency hopping function is also built-in,

which contributes to low EMI. In addition, this product

has a built-in super junction MOSFET which has a

withstand voltage of 730 V.
