Texas Instruments Step-Down Converter for LM5160

An evaluation board demonstrating the performance of the LM5160 step-down regulator from Texas Instruments. The board provides a 5V output from an input of 10 to 60V at load currents of up to 1.5A, with the LM5160 synchronous step-down (buck) regulator IC operating in constant on-time (COT) mode at 300kHz. The PCB allows selection of the PWM operating mode between CCM and DCM (continuous or discontinuous conduction).

• Integrated high- and low-side MOSFETs
• Wide 10 to 60V input voltage range
• 5V output at up to 1.5A load current
• FET place holder for EN/UVLO shutdown feature
• PWM mode select pin for CCM or DCM operation
