TPS43060RTET

The TPS43060RTET is a Low IQ Synchronous Boost Controller with wide input voltage and 7.5V gate drive for standard FETs. Synchronous rectification enables high-efficiency for high-current applications and lossless inductor DCR sensing further improves efficiency. The resulting low-power losses supports high power-density and high-reliability boost converter solutions over extended (-40°C to 150°C) temperature range. The TPS43060 includes a 7.5V gate drive supply, which is suitable to drive a broad range of MOSFETs. It has a 5.5V gate drive supply and driver strength optimized for low Qg NexFET power MOSFETs. Also, TPS43061 provides an integrated bootstrap diode for the high-side gate driver to reduce the external parts count. The PWM control circuitry turns on the low-side MOSFET at the beginning of each oscillator clock cycle, as the error amplifier compares the output voltage feedback signal at the FB pin to the internal 1.22V reference voltage.
