The TPS43060 and TPS43061 are low IQ current-mode synchronous boost controllers with wide-input voltage range from 4.5 to 38 V (40 V absolute max) and boosted output range up to 58 V. Synchronous rectification enables high-efficiency for high-current applications, and lossless inductor DCR sensing further improves efficiency. The resulting low-power losses combined with a 3-mm × 3-mm WQFN-16 package with PowerPAD™ supports high power-density and high-reliability boost converter solutions over extended (–40°C to 150°C) temperature range.

The TPS43060 includes a 7.5-V gate drive supply, which is suitable to drive a broad range of MOSFETs. The TPS43061 has a 5.5-V 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.
