General Description

The PWM type DC/DC converter series for 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.

This series has a built-in HV starter circuit that

tolerates 650V, and it contributes to low power

consumption. With a current detection resistor 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 65 kHz. At light

load, the switching frequency is reduced and high

efficiency is achieved. 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.
