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.
