... Overview The NCP5316 DC/DC controller from ON Semiconductor was developed using the Enhanced combines the original V topology with peak current−mode control for fast transient response and current sensing capability. The addition of an internal PWM ramp and implementation of fast−feedback directly from Vcore has improved transient response and simplified design. This controller can be adjusted to operate as a four− ...

Enhanced V responds to disturbances in V employing both “slow” and “fast” voltage regulation. The internal error amplifier performs the slow regulation. Depending on the gain and frequency compensation set by the amplifier’s external components, the error amplifier will ...

Transient Response and Adaptive Voltage Positioning For applications with fast transient currents, the output filter is frequently sized larger than ripple currents require in order to reduce voltage excursions during load transients. Adaptive voltage positioning can reduce peak−peak output voltage ...
