The G5129 boost converter contains a 0.46Ω internal switch. The IC operates at constant frequency 600 kHz, allowing the use of tiny, low cost and low height inductors and capacitors. The IC operates from a 2.7V to 7V supply voltage. High inrush current at start-up is eliminated using large compensation capacitor. Constant frequency current mode PWM architect.
