TPS43061RTET .

The TPS43061RTET is a low quiescent current-mode synchronous Boost Controller with wide-input voltage range from 4.5 to 38V (40V absolute maximum) and boosted output range up to 58V. Synchronous rectification enables high-efficiency for high-current applications and lossless inductor DCR sensing further improves efficiency. The resulting low-power losses combined with the PowerPAD™ supports high power-density and high-reliability boost converter solutions over extended temperature range. The TPS43061 has a 5.5V gate drive supply and driver strength optimized for low Qg NexFET power MOSFETs. Also, provides an integrated bootstrap diode for the high-side gate driver to reduce the external parts count.
