Texas Instruments TPS43061RTE

Beschreibung

The TPS43060 and TPS43061 are low IQ currentmode synchronous boost controllers with wide input voltage range from 4.5 V to 38 V (40 V abs 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 x 3 mm WQFN-16 package with PowerPAD™ supports high powerdensity 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 anddriver strength optimized for low Qg NexFET™. In addition, TPS43061 provides an integrated bootstrap diode for the high side gate driver to reduce external parts count.
