The FAN5069 is a device that combines a high-efficiency PWM controller and an LDO linear regulator controller. It features high efficiency over a wide range of load currents and adjustable current limit. The device is suitable for applications such as PC/server motherboard peripherals, FPGA, DSP, embedded controllers, graphic card processors, and communication processors.
The FAN5069 is a general-purpose Pulse-Width Modulated (PWM) controller combined with a Low Dropout (LDO) linear regulator controller. It supports synchronous rectification to provide high efficiency over a wide range of load currents and input voltages from 3V to 24V.
Key features include programmable current limits, adjustable switching frequencies between 200kHz and 600kHz, and soft-start capabilities for both the PWM and LDO regulators. The device offers multi-fault protection with an optional auto-restart feature and is available in industrial (-40°C to +85°C) and commercial temperature grades within a 16-pin TSSOP package.
