G5135

Global Mixed-mode Technology Inc. G5135 Micro-Power Boost DC/DC Converter Features „ Operating Voltage：2.7V ~ 5.5V „ High Operating Frequency：1MHz „ Shutdown Current：＜1μA „ High Output Voltage：Up to 40V „ Soft Start Function „ Cycle by Cycle Current Limiting „ SOT-23-5 Package Applications „ STN/OLED BIAS „ Personal Digital Assistants „ DSC „ TV Tunner General Description The G5135 boost converter contains a 0.7Ω internal switch. The IC operates at constant frequency 1MHz, allowing the use of tiny, low cost and low height inductors and capacitors. The IC operates from a 2.7V to 5.5V supply voltage and can boost supply voltage up to 40V at the output. High inrush current at start-up is eliminated using the soft-start function. Constant frequency current mode PWM architecture results in low, predictable output noise. The G5135 includes cycle-by-cycle 850mA current limiting to maximum inductor current and over-temperature protection circuit. The G5135 is suitabl...
