PT6651B

The PT6651B power modules are a series of high efficiency, non-isolated step-down integrated switching regulators (ISRs). These regulators PT6651B are designed to operate over a 9 V to 28 V input voltage range to produce a tightly regulated output voltage at load currents of up to 5 A. The wide input voltage range allows them to operate off either a 12 V or 24 V DC input bus system, making them ideal for general purpose and industrial applications. The series includes standard output voltage options ranging from 15 V down to 2.5 V,and down to 1.8 V with adjustment. Only two external capacitors are required for proper operation.

The PT6651B series is housed in a lowcost 14-pin SIP (Single In-line Package) and is available in both vertical and horizontal configurations, including surface-mount.
