TPS4005x Wide-Input Synchronous Buck Controller
1 Features 3 Description
The TPS4005x is a family of high-voltage, wide-input

• Operating Input Voltage 8 V to 40 V
(8 V to 40 V), synchronous, step-down controllers.
• Input Voltage Feed-Forward Compensation
The TPS4005x family offers design flexibility with a
• < 1% Internal 0.7-V Reference
variety of user-programmable functions, including
soft-start, UVLO, operating frequency, voltage
• Programmable Fixed-Frequency up to 1-MHz

• Internal Gate-Drive Outputs for High-Side and
Synchronous N-Channel MOSFETs
The TPS4005x uses voltage feed-forward control
techniques to provide good line regulation over the
