    Description

    The TPS55332 is a monolithic high-voltage switching regulator with integrated 3-A, 60-V power MOSFET. The device can be configured as a switch mode step-up power supply with voltage supervisor. Once the internal circuits have stabilized with a minimum input supply of 3.6 V, the system can then have an input voltage range from 1.5 V to 40 V, to maintain a fixed boost output voltage. For optimum performance, VIN/Vout ratios should be set such that the minimum required duty cycle pulse > 150 ns. The supervisor circuit monitors the regulated output and indicates when this output voltage has fallen below the set value. The TPS55332 has a switching frequency range from 80 kHz to 2.2 MHz, allowing the use of low profile inductors and low value input and output capacitors.
