FX5545G206

FX5545G206 Vishay Industry Smallest and Low Profile 15W, 2.5A DC/DC Boost 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 550W/inch3 • 1µA shutdown current • 2.7V to 6V input range (1Li+ and 3-cell NiCd or NiMH cells) • 3.3V to 6V output voltage • Programmable PWM/PSM controls • Low output ripple • BGA construction • Temperature range: - 40°C to + 85°C • No external components required • Output power 15W • Maximum current 2.5A • Low profile The DC/DC converter is a programmable topology synchronized Boost 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 2.5V 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. APPLICATION • Point of Load (POL) applications such as drivers for FPGA’s, microprocessors, DSP’s, amplifiers, etc. • Cordless phones, PDA’s and others • Supply voltage source for low-voltage chip sets • Portable computers • Battery back-up supplies • Cameras ORDERING INFORMATION FX FUNCTION SIZE CIRCUIT IDENTIFIER OUTPUT VOLTAGE - Example: 3.3V should be written as 3V3 as the V indicates the decimal point, or ADJ for adjustable version - self selectable output voltage. PACKAGING - B1 = 10pcs in bulk; B5 = 50pcs in bulk; T1 = 13” reel; T2 = 7” reel. For lead (Pb)-free solder please add E2 suffix.
