STD1807
DESCRIPTION
1.5MHz, 1.5A, Synchronous Step Down DC/DC Converter
FEATURE
The STD1807 is a high-efficiency, DC-to-DC
step-down switching regulators, capable of
delivering up to 1.5A of output current. The device
operates from an input voltage range of 2.5V to
6.0V and provides an output voltage from 0.6V to
VIN, making the STD1807 ideal for low voltage
power conversions. Running at a fixed frequency of
1.5MHz allows the use of small external
components, such as ceramic input and output
caps, as well as small inductors, while still providing
low output ripples. This low noise output along with
its excellent efficiency achieved by the internal
synchronous rectifier, making STD1807 an ideal
green replacement for large power consuming
linear regulators. Internal soft-start control circuitry
reduces inrush current. Short-circuit and thermal-
overload protection improves design reliability.
