com 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.
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 FUNCTION SIZE CIRCUIT IDENTIFIER OUTPUT VOLTAGE - Example: 2.
