NCP1378P Application Field and Working Principle

NCP1378P is a high performance low voltage DC DC Switching Controller, which is a type of PMIC – Voltage Regulators. This integrated circuit is specifically designed for battery powered small-signal products and can operate from input voltages as low as 1.2V or as high as 15V. It provides protected current up to 2A (10A peak) from a wide load range and is designed to offer superior load and line regulation, along with a low quiescent current.The NCP1378P is pin compatible with NCP1378N or equivalent parts, making it an ideal choice for cost-sensitive applications. Its small 8 Pin SO-145 package makes it suitable for space constrained applications, and the optional enable pin and adjustable threshold voltage allow the user to easily adjust the output.The NCP1378P has an on-chip shutdown circuit and adjustable output current limiting, both of which can save energy and protect the device from abuse. Its integrated output voltage soft start circuitry helps protect the external MOSFETs and reduces inrush current.This DC DC Switching Controller is suitable for a variety of applications, including battery powered systems, notebook CPUs, digital home entertainment products, mobile phones, PDAs, and portable music players.

Working Principle

The NCP1378P DC DC Switching Controller uses the principle of Pulse Width Modulation (PWM). This state of the art technology is based on the principle that by controlling the frequency and duty cycle of a pulse, a stable output voltage with a low ripple can be achieved.The NCP1378P provides all the necessary pulses and control signals to the external MOSFETS, which then switch according to the controller’s instructions. The MOSFETs control the voltage on the output and the average output voltage equals the input voltage multiplied by the ratio of the on-time divided by the total period.The NCP1378P provides four internal feedback comparators, with three of them used for Power up/Soft start, Low Voltage/Undervoltage protection, and Overvoltage protection, and the fourth one used for Thermal Shutdown. The thermal shutdown comparator is used to prevent the device from overheating and provides thermal protection for the external MOSFETs.Furthermore, the NCP1378P is designed to shut down the output and notify the external processor when the output voltage reaches the peak current limit threshold or when current is not delivered from the input.In conclusion, the NCP1378P DC DC Switching Controller is an efficient, cost-effective PMIC – Voltage regulator that is suitable for a variety of battery powered and other applications. Its on-chip features and reliable performance provide an ideal solution for a range of applications.
