Power Integrations RDK-961 60W Programmable Power Supply
Power Integrations RDK-961 60W Programmable Power Supply features Zero Voltage Switching (ZVS) and 5V to 20V variable output using PowiGaN-based Innoswitch4-Pro (INN4373F-H341), ClampZero (CPZ1075M), and a Microchip™ microcontroller (PIC16F18325). The Power Integrations RDK-961 delivers high efficiency (greater than 90% across the load range) while minimizing losses through advanced digital control and zero-voltage switching. The RDK-961 includes integrated protection against overvoltage, overcurrent, and thermal conditions. The 3.35” x 2.0” x 0.83” compact form factor is optimized for chargers/adapters, tool/eBike chargers, and USB PD adapters.
