8.1 Application Information

The TPS7H4010-SEP device is a step-down DC-DC voltage regulator. It is designed to operate with a wide supply voltage range (3.5 V to 32 V), wide switching frequency range (350 kHz to 2.2 MHz), and wide output voltage range: up to 95% VIN. The TPS7H4010-SEP is a synchronous converter with both HS and LS MOSFETs integrated, and it is capable of delivering a maximum output current of 6 A. The following design procedure can be used to select component values for the TPS7H4010-SEP. This section presents a simplified discussion of the design process.
