Product description:
High Performance Resonant Mode Controller ICE2HS01G in PG-DSO-20 package
The ICE2HS01G is a high performance resonant mode controller designed for high efficiency half-bridge or full-bridge LLC resonant converters with synchronous rectification on the secondary side. With its new drive technology, the LLC converter can achieve synchronous rectification with a second switch current operating under CCM and DCM conditions. No special synchronous rectification controller IC is required on the secondary side. The maximum supported switching frequency is up to 1MHz. The IC offers a very flexible design and integrates complete protection functions. It adjusts the maximum/minimum switching frequency, soft-start time and frequency, dead time between primary switches, and turn-on and turn-off delays of the secondary SR MOSFETs. Integrated protection includes input voltage brownout, primary tertiary overcurrent, secondary overload protection and no-load regulation. For best performance, it is recommended to use a half-bridge driver IC on the primary side of the ICE2HS01G.
Applications:
PC power supplies, Server power supplies, Telecom power supplies, Flat-panel TV and Flat panel display power supplies, AC-DC adapter.
