SLUSDL0A January 2020 – March 2020 TPS59603-Q1
PRODUCTION DATA.
The TPS59603-Q1 device is a synchronous-buck MOSFET driver designed to drive both high-side and low-side MOSFETs. It allows high-frequency operation with current driving capability matched to the application. The integrated boost switch is internal. The TPS59603-Q1 device employs dead-time reduction control and shoot-through protection, which helps avoid simultaneous conduction of high-side and low-side MOSFETs. Also, the drivers improve light-load efficiency with integrated DCM-mode operation using adaptive crossing detection. Typical applications yield a steady-state duty cycle of 60% or less. For high steady-state duty cycle applications, including a small external Schottky diode may help to ensure sufficient charging of the bootstrap capacitor.
