HIGH VOLTAGE HIGH-FREQUENCY STEP-UP SWITCHING REGULATOR-CONTROLLER

The IL700D is a monolithic high voltage switching regulator-controllers with

PWM/PFM control that is specifically designed to operate from a rectified 220 VAC

line source. This device contain a reference voltage source, oscillation circuit, error

amplifier, phase compensation circuit, PWM control circuit, power supply 450 V

MOS-transistor, 700 V DMOS power switch, and other components. Since the

oscillation frequency is a high 600 kHz, with the addition of a small external

component, the IC can function as switching regulator with high efficiency.

The IL700D provides low-ripple power, high-efficiency, and excellent transient

characteristics thanks to a PWM control circuit capable of varying the duty ratio linearly

from 0% to 82% and optimized error amplifier, and phase compensation circuit.

The IL700D contains a PWM/PFM switching control circuit so that it operates

using PWM control with a duty ratio of 27% or higher and using PFM control with a

duty ratio of lower than 27% to ensure high efficiency in all load ranges.
