■ General Purpose PWM Regulator and LDO Controller The FAN5069 combines a high-efficiency Pulse-Width- ■ Input Voltage Range: 3V to 24V Modulated (PWM) controller and an LDO (Low DropOut) ■ Output Voltage Range: 0.8V to 15V – VCC N – 5V IG ■ Shunt Regulator for 12V Operation ES ■ Support for Ceramic Cap on PWM Output D D ■ Programmable Current Limit for PWM Output W ■ Programmable Switching Frequency (200KHz to E E 600KHz) N ■ RDS(ON) Current Sensing U R ■ Internal Synchronous Boot Diode FO mi N ■ Soft-Start for both PWM and LDO IND se IO ■ Multi-Fault Protection with Optional Auto-restart E n T ■ 16-pin TSSOP Package T ND R o MA Applications ME OU OR ■ PC/Server Motherboard Peripherals NM Y F – VCC_MCH (1.5V), VDDQ (1.5V) and O T IN VTT_GTL (1.25V) O C C R ■ Power Supply for RE TA O – FPGA, DSP, Embedded Controllers, Graphic Card C T N F Processor, and Communication Processors O O E ■ Industrial Power Supplies N C IV ■ High-Power DC-to-DC Converters linear regulator controller.
Synchronous rectification provides high efficiency over a wide range of load currents.
Efficiency is further enhanced by using the low-side MOSFET’s RDS(ON) to sense current.
