Description
High‑Efficiency Compact Charging Module for Portable Systems
Deliver reliable power to a wide variety of low‑power devices with this integrated DC‑DC charging module. Designed for use in battery‑powered electronics, industrial sensors and IoT nodes, it converts a higher input voltage (sourced from mains or a larger battery bank) into a stable, low‑voltage supply that charges small Li‑ion or Li‑poly cells safely and efficiently.
The module incorporates a synchronous buck‑boost controller, a 2‑DCDC resonant converter topology, and built‑in over‑current, over‑voltage and temperature protection. Its modular PCB footprint and 1‑in. case make it easy to replace or upgrade in existing systems without redesigning the chassis.
- Key Spec 1: Input: 5‑35 V DC; Output: 3.7 V DC @ up to 3 A
- Key Spec 2: 95 % peak efficiency at 1 A load; ripple < 30 mV
- Key Spec 3: Integrated 4 kΩ sense resistor; autonomous “self‑monitor” for fault conditions
- Common Use Case: Rechargeable battery packs in handheld communication devices and embedded remote sensors
