FX5545G106 Vishay Industry Smallest and Low Profile 10W 2A DC/DC Boost Converter with High Output Density Power FEATURES • Fully integrated DC/DC converter • High efficiency over large load range • 100% duty cycle • Power density - more than 380W/inch3 • 1uA 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 needed • Output power 10W • Maximum current 2A • 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 input voltage range of 2.5V to 6V. An additional flexibility is provided with topology programmibility to power multiple loads such as power amplifiers, microcontrollers, or base band 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 • • • • • Cordless phones, PDAs and others Supply voltage source for low-voltage chip sets Portable computers Battery back-up supplies Cameras ORDERING INFORMATION FX 5545 G106 FUNCTION SIZE CIRCUIT IDENTIFIER 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.
