The TPQ80302 is a nonsynchronous switching boost converter with an integrated 80-V, 110-mΩ power switch, and a 2.1-Ω load switch. The device can be configured in several standard switching-regulator topologies, including boost, SEPIC, and flyback. The device has a wide input voltage range up to 80 V to support applications with input voltage from multicell batteries or 5-V, 12-V, 24-V, and 48- V power rails. The TPQ80302 regulates the output voltage with peak current mode pulse width modulation (PWM) control. The switching frequency is programmable from 100 kHz to 2.2 MHz by an external resistor. The TPQ80302 integrates a 80-V, 2.1-Ω load switch to disconnect the load from input voltage during shutdown. With the load switch, the device features adjustable DC startup charging current. When the output voltage is close to the input voltage, the device goes into switching mode soft startup. The TPQ80302 has hiccup mode output short circuit protection when the output voltage at the VOUT pin is below the input voltage. The device also features cycle-bycycle current limit in over-load condition. The TPQ80302 is available in a 20-pin 3.5x3.5 QFN package with exposed thermal pad.
