Abstract
An emulated peak current mode control (EPCMC) synchronous buck converter device is provided, and may include a converter having an inductor, a high-side switch, and a low-side switch, and an EPCM controller. The controller may include a PWM latch to alternately turn on and off the high-side and low-side switches, a current sense element to output a current sense voltage based on the inductor current, and a feedforward circuit to generate a feedforward voltage. The current sense element outputs a first current sense voltage while the low-side switch is turned on, and outputs a second current sense voltage while the low-side switch is turned off. The feedforward voltage is generated based on a voltage differential that represents a difference between the first current sense voltage and the second current sense voltage, and the PWM latch alternately turns on and off the high-side and low-side switches based on the feedforward voltage.
