Radiation Hardened 5VIN to 1.2VOUT Point-of-Load Regulator Mini Demonstration Board

The ISL73006SLHDEMO1Z demonstration board provides a quick and easy method for evaluating the ISL73006SLH radiation hardened point-of-load (POL) buck regulator in the internal compensation configuration.

The ISL73006SLH buck regulator is a small footprint radiation hardened POL designed for critical low-power applications. It is operational over 3V to 18V, integrating high-side and low-side power FETs and switches at a default 500kHz frequency. The ISL73006SLH uses a constant-frequency peak current mode control architecture for fast loop transient response. The device can use its internal compensation or an external Type II compensation to stabilize the loop as determined by specific design and performance requirements.

By integrating both P-channel and N-channel power devices, and with the option of internal compensation, minimal external components are required, thereby reducing the BOM count and complexity of the design.
