Radiation Hardened 12VIN to 3.3VOUT Point-of-Load Regulator Evaluation Board

The ISL73006SLHEV1Z evaluation board provides a quick and easy method to evaluate the ISL73006SLH radiation hardened point-of-load (POL) buck regulator in an internal or external compensation configuration.

The ISL73006SLH buck regulator IC is a small footprint radiation hardened POL designed for critical low-power applications. It is operational over 3V to 18V, integrating both high-side and low-side power FETs and switches at a native 500kHz frequency. The ISL73006SLH uses a constant-frequency peak current mode control architecture for fast loop transient response. The ISL73006SLH can use either 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.
