Overview

The TPQ5057xQ (TPQ5057Q and TPQ50571Q) is a wideinput-range, non-synchronous boost converter with an integrated 48-V, 7-A power switch. The device can be used in boost, SEPIC, and flyback topologies.

The TPQ5057xQ uses a peak current control scheme. The device can start up from a minimum voltage of 2.9 V. When the VIN pin is powered by an auxiliary supply voltage above 2.9 V, the supply voltage for the power stage can be down to 1.5 V.

The TPQ5057xQ integrates a wide input LDO that supports the input voltage of up to 45 V for automotive load dump and outputs 5 V at the VCC pin. The switching frequency is either set by an external resistor or synchronized to an external clock from 100 kHz to 2.2 MHz. Switching at 2.2 MHz minimizes AM band interference and allows for a small solution size and fast transient response. The TPQ5057xQ supports the use of an external VCC supply to improve efficiency. Low operating current and pulse-skipping operation improve efficiency at light loads.

The device has built-in protection features such as cycleby-cycle current limit, overvoltage protection, hiccup mode overload protection, and thermal shutdown. Additional features include low shutdown current, programmable soft start, programmable input UVLO, spread spectrum, and power-good indicator.

The TPQ5057xQ is available in a QFN3x3-16 package.
