Description :

The L6598 device is manufactured with the BCD™ offline technology, able to ensure voltage ratings up to 600 V, making it perfectly suited for AC/DC adapters and wherever a resonant topology can be beneficial. The device is intended to drive two power MOSFETs, in the classical half bridge topology. A dedicated timing section allows the designer to set soft-start time, soft-start and minimum frequency. An error amplifier, together with the two enable inputs, are made available. In addition, the integrated bootstrap diode and the Zener clamping on low voltage supply, reduces to a minimum the external parts needed in the applications.

HS01G Datasheet – Half-Bridge Resonant Controller – Infineon

Part Number: HS01G, ICE1HS01G

Function: Half-Bridge Resonant Controller

Package : DSO8 Type

Manufacturer: Infineon Technologies

HS01G controller ic

Description

The controller ICE1HS01G with two gate outputs is specially designed for LLC resonant half-bridge converters. An oscillator with accurately-programmed frequency range is built inside the IC. The two gate signals are obtained by passing the signal out from the oscillator through a divide-by-two flip-flop. Therefore, two signals are of exactly 50% duty cycle and 180′ out of phase. To guarantee the zero-voltage-switching and safe operation in half-bridge topologies, a fixed dead time of 380ns is inserted in each internal when one switch is turned off and the other is turned on.
