描述
The ISL73007SEHEV2Z evaluation board features the ISL73007SEH buck regulator. The IC is a small footprint radiation hardened POL designed for critical low-power applications.
The ISL73007SEH is operational over 3V to 18V, integrating both high-side and low-side power FETs and switches at a default 500kHz frequency. The switching frequency can also be programmed from 300kHz up to 1MHz using an external resistor. The ISL73007SEH uses a constant-frequency peak current mode control architecture for fast loop transient response. The ISL73007SEH can use either its internal compensation at the 500kHz default switching frequency or an external Type II compensation at other frequencies to stabilize the loop as determined by specific design and performance requirements. When integrating both P-channel and N-channel power devices with the option of internal compensation, a minimum of external components is required, thereby reducing the BOM count and complexity of the design.
The ISL73007SEHEV2Z evaluation board is optimized for converting 12V input voltages down to 3.3V-1.2V output.
