The charger with nickel cadmium, nickel metal hydride rechargeable lithium ion batteries, converted, and has a discharge function. In 150 ~ 250 V, 40 mA communication utility the input, output 300 + 50 mA dc current. The charger using RCC switch power supply, namely the oscillation inhibited type converter, it and PWM switch power supply has a certain difference. PWM switch power supply by independent sampling error amplifier and dc  amplifie  composition pulse width modulation system; And RCC type switch power is just a stabilizer composition level switches and control process for oscillation condition and check status. Mobile Phone Universal Charger Electronic Circuit Diagram And Working Principle
