Buck regulator boosts transient response and stability
Kinetic’s KTB4800 2.4-MHz, 3-A buck regulator delivers fast transient response with precise switching frequency. Its OptiComp adaptive on-time PWM control scheme maintains a nearly constant switching frequency despite input and output voltage variations.
Compared to typical current-mode PWM schemes, OptiComp enables quick response to line and load transients while ensuring excellent stability and wide bandwidth. This reduces output voltage droop and overshoot for dynamic loads, even with minimal output capacitance.
The KTB4800 buck regulator supports a range of applications, including CPU and GPU cores, DSPs, DDR memory, I/O power, and sensor/analog supplies. Its output voltage is I²C-programmable from 0.6 V to 3.345 V. The regulator features soft-start and dynamic voltage scaling (DVS) with multiple programmable ramp rates, along with selectable forced-PWM and auto-skip modes for light-load efficiency.
The KTB8400 OptiComp switching regulator is available now for order from Mouser Electronics and other distributors.
