Description

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.
