Product detailed description

Power module MATEKSYS PM20S-2

MATEKSYS PM20S-2 is a high-power dual-output DC-DC power module designed to provide stable and efficient power for demanding RC, UAV and drone electronics. It features two independent synchronous step-down regulators with selectable output voltages, high current capability and built-in protection functions.

Features:
- Dual Independent Regulators: Provides two separate power outputs, allowing different onboard devices to be supplied with the voltage they require
- Wide Input Compatibility: Designed for high-voltage power systems and suitable for a broad range of battery configurations
- High Current Capability: Delivers substantial continuous and peak current for demanding servos, flight controllers and other power-hungry electronics
- Efficient Power Conversion: Synchronous buck regulator technology provides efficient voltage conversion with reduced power loss 
- Selectable Output Voltages: Each regulator offers several predefined voltage options for flexible system configuration
- High-Voltage Protection: Built-in TVS protection helps protect the module against high input-voltage transients
- Overcurrent Protection: Automatically recovers after an overcurrent condition, helping protect connected electronics
- Thermal Protection: Thermal shutdown protects the regulators from excessive temperature
- Voltage Monitoring: An integrated voltage divider allows the input voltage to be monitored through a 3.3V-based ADC
- Compact Design: High-power regulation is packed into a compact and lightweight board suitable for space-constrained UAV and RC installations
