JP6020 Series Chip

> Products > JP6020 Series Chip

JP6020 - A highly configurable SMPS controller for the secondary side regulation.

It provides the necessary functions and protections for high efficiency and high power density off-line AC-DC converter designs. The JP6020 integrates an MCU and is able to handle various proprietary protocols such as SCP and USB PD through D+/D- and CC1/CC2 pins. A wide output voltage range of 3V to 24V is achievable. Dual operational amplifiers with respectively programmable reference voltages are included for voltage-loop and current-loop regulation to provide programmable constant-voltage (CV) and constant-current (CC) regulation in high precision.
