PM20S-2 Dual Step-Down Voltage Regulator

The PM20S-2 is a powerful and versatile dual step-down voltage regulator designed to handle demanding applications with ease. Built with 100V DC components, this regulator supports a wide input voltage range from 9V to 85V DC, with 85V TVS protection for enhanced safety and reliability.

Featuring two independent regulators, the PM20S-2 offers multiple output voltage options. Regulator 1 provides 5.3V, 6.1V, or 8.1V outputs, while Regulator 2 offers 5.3V, 8.1V, or 12.2V outputs. Both regulators support a typical continuous output current of up to 15A and a peak current of up to 22A, making it ideal for high-current applications. With efficiencies ranging from 90% to 96%, it ensures minimal power loss during operation.

This compact module, measuring 61x40x15mm and weighing just 63g, is designed with a 1K:25K voltage divider for 3.3V ADC compatibility. The PM20S-2 also includes key protection features such as thermal shutdown, overcurrent protection with self-recovery, and short-circuit tolerance, making it a reliable choice for your power management needs.
