In the application field of TPS62160EVM-627, the most commonly found applications are distributed on-chip power regulation for low-voltage buses, ASIC/ASSP core circuits and FPGA/microcontroller regulators, DDR memory powering, and xDSL and networking infrastructure powering. It is also capable of driving a wide range of power-supply topologies including 1V-4V at 5A and 0V-3.3V at 9.5A.

The working principle of TPS62160EVM-627 depends on the TPS62160 controller as well as other components. In a typical application circuit, when power is first applied, the controller enables the external MOSFET, which turns on the input power source. The external resistor divider connected to the regulator’s FB and BST pins then feeds back the feedback voltage to the VFB pin. The controller and the selected voltage feedback set the output voltage according to the feedback voltage.

The internal clock of the controller determines the pulse width modulation (PWM) frequency. The internal duty-cycle modulator then adjusts the duty cycle of the PWM signal as needed to maintain the output voltage at the set point. The PWM signal then drives the external MOSFET to control the voltage and current of the output. All of these components together are what enables the TPS62160EVM-627 to deliver efficient single output 5A DC/DC buck converter with reduced component count.

It is a versatile solution that can be used in a wide range of applications. This includes low voltage on-chip power regulation for microcontrollers, ASICs/ASSPs, FPGAs, and DDR memory powering. With its high efficiency and low component count, the TPS62160EVM-627 is sure to become the go-to solution for distributed on-chip power regulation and power supply topologies.
