The working principle of the NCP51198 PDR2G is similar to that of other conventional synchronous voltage regulators. In this voltage regulator, the MOSFETs switch the main power transistors in order to provide the desired output voltage. The output voltage is controlled by the current-mode control loop, which consists of a current comparator, a duty cycle regulator, and a feedback divider. The duty cycle regulator ensures that the desired duty cycle is maintained for the MOSFETs, while the comparator compares the output current to the reference current and adjusts the MOSFET duty cycle accordingly. The feedback divider is used to provide the feedback signal to the error amplifier, which uses this signal to compare the output voltage to the reference voltage and thus set the appropriate duty cycle.

Overall, the NCP51198 PDR2G is designed to provide robust, low-noise power supply solutions for today’s portable and battery-driving applications. With its wide input voltage range, high current delivery, excellent line- and load-transient response, and low output voltage ripple and EMI noise, the NCP51198 is the ideal choice for a number of different applications. Furthermore, its accurate current-mode control architecture ensures excellent thermal performance, making it suitable for even the most demanding power applications.
