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 • Cordless phones, PDAs and others • Supply voltage source for low-voltage chip sets • Point of Load (POL) applications such as drivers for FPGA’s, microprocessors, DSP’s amplifiers, etc. • Portable computers • Battery back-up supplies • Cameras ORDERING INFORMATION FX 5545 G008 FUNCTION SIZE CIRCUIT IDENTIFIER - G008 or G018 OUTPUT VOLTAGE - Example: 1.2V should be written as 1V2 as the V indicates the decimal point or ADJ for adjustable version - self selectable output voltage. G018ADJ is only available in the adjustable version for Vout = 0.9V - 1.3V.
