FX5545 GXXX XXX PI Vishay Fully Integrated DC/DC Converter 0.9V to 6V, 3A with 380W/in3 Density Power Efficiency up to 95% or Simplified LAB assembly configuration for all models FEATURES * Specially designed for prototyping in LABs with limited assembly equipment. * Fully integrated DC/DC converter * No external components required * Buck and Boost configurations * High efficiency over large load range * 100% duty cycle * Power density - more than 380W/inch3 * 1A shutdown current * 2.5V to 6V input range (1Li+ and 3-cell NiCd or NiMH cells) * 0.9V to 6V output voltage * Programmable PWM/PSM controls * Low output ripple The DC/DC converter is a programmable topology synchronized Buck or Boost converter for today's continuous changing 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 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 for production. Convenient 8-pin plug-in modules are available for prototyping. In order to satisfy the stringent ambient temperature requirements, the DC/DC converter is designed to handle the industrial temperature range of - 40C to + 85C, with no cooling or derating * Standard socket construction or plug-in for prototype (use BGA for production) * Temperature range: - 40C to + 85C * Output power 10W * Maximum continuous current 3A 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 G PI 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.

PWM/PSM SYNC Logic high =PWM mode, logic low =PSM mode. In PSM mode synchronous rectification is disabled. Externally controlled synchronization signal. Logic high to low transition forces the clock synchronization. If not used the pin must be connected to Vin or logic high. Vin Input supply voltage Vout Output voltage GND Ground Rext. Included inside the package for all fixed output voltage converters. To be added externally for all self-selected output voltages.
