Intersil ISL73007SEHEV2Z Manual

ISL73007SEHEV2Z
The ISL73007SEHEV2Z evaluation board (shown in
Figure 3) features the ISL73007SEH
The IC is a small foot print 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 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 are required, thereby reducing
the BOM count and complexity of the design.
The ISL73007SEHEV2Z evaluation board and this
accompanying manual provide a quick and easy
method to evaluate the ISL73007SEH part, see the
ISL73007SEH datasheet for information about the
operation, function, and performance of the device.

Specifications
The ISL73007SEHEV2Z evaluation board is by
default externally configured for immediate evaluation
with minimum components and connections, which
allows for other conditions to be evaluated with
user-modification of components and connections.
