Features
- a trimmed oscillator for precise Duty Cycle control, accurate bandgap voltage reference, high gain error amplifier, current sensing comparator and a high current totem pole output gate driver that ideally drives the external power MOSFET. Additionally, the device has built--in programmable Brownout Detect and Soft--Start features to enhance system reliability. Also, the 48%/82% selectable maximum turn on Duty Cycle control and external programmable switching frequency capabilities make this devi.
