End of Life, for last available purchase date please see www.vishay.com/integrated-modules FX5545G305 FX5545G305 Vishay Industry Smallest and Low Profile 10W 3.0A DC/DC Buck Converter with High Output Power Density FEATURES · Fully integrated DC/DC converter · High efficiency over large load range · 100% duty cycle · Power density - more than 380W/inch3 · 1µA shutdown current · 2.7V to 6V input range (1Li+ and 3-cell NiCd or NiMH cells) · 1.35V to 4.5V* output voltage · Programmable PWM/PSM controls · Low output ripple · BGA/LGA construction · Temperature range: - 40°C to + 85°C · No external components needed · Output power 10W · Maximum current 3.0A · Low profile · UL recognized component E250930 E250930 The DC/DC converter is a programmable topology synchronized Buck converter for today's continuous changing portable electronic market. The DC/DC converter provides flexibility of utilizing various battery configurations and chemistries such as NiCd, NiMH, or Li+ with an input voltage range of 2.7V to 6V. An additional flexibility is provided with topology programmability to power multiple loads such as power amplifiers, microcontrollers, or baseband logic IC's. For ultra-high efficiency, converters are designed to operate in synchronous rectified PWM mode under full load while transforming into externally controlled pulse-skipping mode (PSM) under light load. The DC/DC converter is available in 20-ports BGA package. In order to satisfy the stringent ambient temperature requirements, the DC/DC converter is designed to handle the industrial temperature range of - 40°C to + 85°C. *Note: For higher output voltage please consult factory at FunctionPAK@Vishay.com APPLICATION · Point of Load (POL) applications such as drivers for FPGA's, microprocessors, DSP's amplifiers, etc. · Cordless phones, PDAs and others · Supply voltage source for low-voltage chip sets · Portable computers · Battery back-up supplies · Cameras · Routers · Fiber optics · LANS · Image processing ORDERING INFORMATION FX 5545 G305 FUNCTION SIZE CIRCUIT IDENTIFIER OUTPUT VOLTAGE - Output Voltage-Example: 2.7V should be written as 2V7 as the V indicates the decimal point, or ADJ for adjustable version - self selectable output voltage.
