onsemi PMIC - PMIC - Power Supply Controllers, Monitors - FAN7688SJX FAN7688SJX

The FAN7688SJX is an advanced Pulse Frequency Modulated (PFM) controller designed for LLC resonant converters with synchronous rectification. It features a current mode control technique that enhances transient response and simplifies feedback loop design. The device operates within a wide frequency range of 39 kHz to 690 kHz and includes green functions to improve efficiency at light loads, such as symmetric PWM control and the ability to disable synchronous rectification. Protection features include over-current protection, output short protection, non-zero voltage switching prevention, and over-temperature protection, all with auto-restart capabilities. The FAN7688SJX supports a wide operating temperature range from -40¬8C to +125¬8C, making it suitable for various applications, including desktop power supplies, telecom power supplies, and high-efficiency isolated DC-DC converters. The device is packaged in an SOP16 format and is available in a reel with a quantity of 2000 units per package.
