The output voltage of the converter can be precisely regulated to as low as 0.8V, with a maximum tolerance of 1% over temperature and line voltage variations. The ISL6522 provides simple, single feedback loop, voltagemode control with fast transient response. It includes a 200kHz free-running triangle-wave oscillator that is adjustable from below 50kHz to over 1MHz. The error amplifier features a 15MHz gain-bandwidth product and 6V/s slew rate which enables high converter bandwidth for fast transient performance. The resulting PWM duty ratio ranges from 0100%. |
