Immense Advance Tech.
The AT7170 is a high-efficiency, DC-to-DC
step-down switching regulator, capable of delivering
up to 1A of output current. The devices operate from
an input voltage range of 2.6V to 5.5V and provide
output voltages from 0.6V to VIN, making the
AT7170 ideal for low voltage power conversions.
Running at a fixed frequency of 1.5MHz allows the
use of small inductance value and low DCR
inductors, thereby achieving higher efficiencies.
Other external components, such as ceramic input
and output caps, can also be small due to higher
switching frequency, while maintaining exceptional
low noise output voltages. Built-in EMI reduction
circuitry makes this converter ideal power supply for
RF applications. Internal soft-start control circuitry
reduces inrush current. Short-circuit and
thermal-overload protection improves design
AT7170 is housed in a tiny SOT25 package.
