PT6654F [Texas Instruments]

The PT6650 power modules are a series of high efficiency, non-isolated step-down integrated switching regulators (ISRs). These regulators 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 PT6650 series is housed in a low-cost 14-pin SIP and is available in both vertical and horizontal configurations, including surface-mount.
