Abstract

A fully integrated solar charger controller is presented in this paper. The charger has wide input voltage range about 10V to 28V for the solar-powered panel. The input loop regulation is used here as the MPPT protection. This charger also provides different kinds of battery voltages about 4V to 12V. The controller system uses just one error amplifier and no external compensation components is needed. Besides, this controller has 600 kHz PWM modulation and offers the over-current/overvoltage protection. Other components like bandgap, reference generator, saw-tooth generator, register controller and driver circuits are all implemented in this circuit. This chip is fabricated in a 0.4-μm 5V/40V 2P4M process. The power consumption of this full-integrated solar charger controller IC is about 10mA.
