OKI-78SR-5/1.5-W36-C
Overview
The OKI-78SR-5/1.5-W36-C is a compact switching DC-DC converter intended as a drop-in, high-efficiency replacement for linear 5V regulators. It accepts 7 V to 36 V input and provides a regulated 5 V output at up to 1.5 A (approx. 8 W). The module includes short-circuit protection and is specified for operation from -40 C to 85 C.
Why Choose This Part
Compared with linear 5 V regulators, this module delivers much higher efficiency, dramatically reducing power dissipation and the need for heat sinking. Its wide 7 V to 36 V input range and compact package make it a convenient drop-in replacement on designs originally centered on linear regulators. Built-in short-circuit protection improves robustness in fault conditions.
Applications
Key Specifications
Getting Started
No development board or IDE is required. When integrating, follow the manufacturer's datasheet for recommended input and output decoupling, observe correct polarity, and test first with a current-limited bench supply. Verify thermal performance on your board under expected load and ambient conditions, and ensure the input voltage stays above the 7 V minimum.
