Internal Functional Blocks PIN FUNCTIONS Buck Supply, VIN_D This is an input power source for the internal high-side MOSFET of the switch-mode power supply. Phase Node for Buck Regulator, PH This terminal provides the floating voltage reference for the internal drive circuitry. Bootstrap, BOOT The ceramic capacitor on this pin acts a as a voltage supply for the internal high-side MOSFET gate-drive circuitry. The capacitor connects between the BOOT and PH terminals. Operating with a duty cycle of 100% automatically reduces the duty cycle to approximately 95% on every fifth cycle to allow this capacitor to recharge. Voltage-Sense Node, VSENSE An internal resistor between VREG and this pin and another internal resistor between this pin and ground form the voltage-sense network. This terminal is the inverting input for the error amplifier of the control loop. This input is compared to an internal reference of 2 V for the control circuitry.
