IDP2308数据手册集成电路（IC）的PFC（功率因数校正）规格书PDF

描述 Description

The IDP2308 is a multi-mode PFC and LLC controller combined with a floating high side driver and a startup cell. A digital engine provides advanced algorithms for multi-mode operation to support highest efficiency over the whole load range. A comprehensive and configurable protection feature set is implemented. Only a minimum of external components are required with the low pin count DSO-14 package. The integrated HV startup cell and advanced burst mode enable to achieve low stand-by power. In addition a one-time-programming (OTP) unit is integrated to provide a wide set of configurable parameters that help to ease the design in phase.

特性 Features

• Multi-mode PFCConfigurable PFC gate driver
• Synchronous PFC and LLC burst mode control
• Configurable non-linear LLC VCO curve
• Configurable soft-start
• VAC input voltage sensing and X cap discharge via HV pin

优势:
• Integrated 600V startup cell
• Integrated floating driver based on coreless transformer technology
• Digital multi-mode operation for higher efficiency curve
• Supports low stand-by power by means of direct X-cap discharge function and advanced burst mode control
• Eliminates the auxiliary power supply by means of integrated startup cell and burst mode
• UART interface for communication and in-circuit configuration
• Flexible design-in by means of one time programming capability for a wide range of parameters

应用 Application

• LCD-TV 75W ~ 300W
• General SMPS

简介

IDP2308属于集成电路（IC）的PFC（功率因数校正）。由制造生产的IDP2308PFC（功率因数校正）功率因数校正 (PFC) 是用于调整交流电路中的电压和电流之间的相位角，使之趋近于零的半导体器件。不同模式包括平均电流、边界导通、连续导通、临界导通、电流控制式频率折返、不连续和不连续导通，开关频率从 6 kHz 至 1.7 MHz 可调。
