FAN5069
FAN5069 is PWM and LDO Controller Combo manufactured by Fairchild Semiconductor.
Features Description - General Purpose PWM Regulator and LDO Controller The FAN5069 bines a high-efficiency Pulse-Width- - Input Voltage Range: 3V to 24V Modulated (PWM) controller and an LDO (Low Drop Out) - Output Voltage Range: 0.8V to 15V - VCC - 5V IG - Shunt Regulator for 12V Operation ES - Support for Ceramic Cap on PWM Output - Programmable Current Limit for PWM Output - Programmable Switching Frequency (200KHz to E E 600KHz) - RDS(ON) Current Sensing - 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) - Power Supply for RE TA O - FPGA, DSP, Embedded Controllers, Graphic Card C T N F Processor, and munication Processors - 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. Both the linear and PWM regulator soft-start are controlled by a single external capacitor, to limit in-rush current from the supply when the regulators are first enabled. Current limit for PWM is also...
