L6564H ST Power Factor Correction IC | 14-SO | 10V-22.5V Supply, 50kHz-130kHz

Product Overview

The L6564H is a highly integrated, current-mode Power Factor Correction (PFC) controller from STMicroelectronics, designed for medium-to-high power AC-DC converters. It operates in Transition Mode (TM) and features a proprietary multiplier that ensures near-unity power factor and low total harmonic distortion (THD). The device is housed in a compact 14-SO package, making it suitable for space-constrained applications such as LED lighting, adapters, and industrial power supplies.

Detailed Technical Specifications

Key Features

• Transition-mode PFC controller with proprietary multiplier for high PF and low THD
• Very low start-up current (30 µA) and low quiescent current (3.5 mA)
• High output drive capability (±600 mA) for fast MOSFET switching
• Comprehensive protection: overvoltage, brownout, feedback disconnection, and boost inductor saturation
• THD optimizer circuit to minimize line current distortion
• Internal 1.5 ms soft-start for reduced stress during startup
• External disable function for standby operation

Target Applications

• AC-DC adapters for laptops and gaming consoles (e.g., 65W USB-C PD adapter)
• LED street lighting drivers (e.g., 150W constant current driver)
• Industrial power supplies for 5G base stations (e.g., 48V/300W rectifier)
• Home appliance power boards (e.g., air conditioner inverter PFC stage)
• Battery chargers for electric vehicles (e.g., 3.3 kW on-board charger)
