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

The ISL73006SLHDEMO2Z demonstration board provides a quick and easy method for evaluating the ISL73006SLH radiation hardened point-of-load (POL) buck regulator in the external compensation and slope 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 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, a minimum of external components are required, thereby reducing the BOM count and complexity of the design.
