3 Description
The TPS43060 and TPS43061 are low IQ currentmode
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 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 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.
