ISL73007SEHDEMO3Z
The ISL73007SEHDEMO3Z demonstration board
(shown in
Figure
3) features the
regulator. This 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. 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
BOM count and complexity of design.
The ISL73007SEHDEMO3Z demonstration 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 ISL73007SEHDEMO3Z demonstration 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.

    ISL73007SEHDEMO3Z Demonstration Board Manual Basic Layout The ISL73007SEH is located in the center of the board and is labeled U1. Input power is to be connected across the yellow Tantalum capacitor, the bulk input capacitance (C ) at the PVIN and GND pads. The output voltage then appears across the V_OUT and GND pads near the output inductor (L ) and the output capacitance (C respectively.
