Product Overview
LTC3863 is a robust, inverting DC/DC PMOS controller optimized for automotive and industrial applications. It drives a P-channel power MOSFET to generate a negative output and requires just a single inductor to complete the circuit. Output voltages from –0.4V to –150V are typically achievable with higher voltages possible, only limited by external components. The LTC3863 offers excellent light load efficiency, drawing only 70μA quiescent current in a user programmable burst mode operation. Its peak current mode, constant frequency PWM architecture provides for good control of switching frequency and output current limit. The switching frequency can be programmed from 50KHz to 850KHz with an external resistor and can be synchronized to an external clock from 75KHz to 750KHz. The LTC3863 offers programmable soft-start or output tracking. Applications include industrial and automotive power supplies, telecom power supplies and distributed power systems.
- Overvoltage, overcurrent and short-circuit protection including frequency foldback
- Wide operating VIN range from 3.5V to 60V
- Wide negative VOUT range from -0.4V to beyond -150V
- Low operating IQ = 70µA, strong high voltage MOSFET gate driver
- Constant frequency current mode architecture, verified FMEA for adjacent pin open/short
- Selectable high efficiency burst mode operation or pulse-skipping mode at light loads
- Accurate current limit, programmable soft-start or voltage tracking
- Internal soft-start guarantees smooth start-up
- Low shutdown current of 7µA
- 12-lead plastic MSOP package, -40°C to 150°C temperature range
