GS5592
GS5592
3MHz, 2A Synchronous Step-Down Converter
Product Description
The GS5592 is a high-efficiency, DC-to-DC
step-down switching regulator, capable of
delivering up to 2A 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 GS5592 ideal for low voltage power
conversions.
Running at a fixed frequency of 3MHz 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
reliability.
GS5592 is housed in a tiny SOT23-5L and
DFN2x2-8L package

Description
Supply Voltage. Short to PIN. Bypass with a 10μF ceramic capacitor to GND.
Enable pin for the IC. Drive this pin to high to enable the part, low to disable.
Ground Pin.
Inductor Connection. Connect an inductor Between SW and the regulator output.
Feedback Input. Connect an external resistor divider from the output to FB and GND
to set the output to a voltage between 0.6V and VIN.
Power Ground. Bypass with a 10μF ceramic capacitor to PVIN.
Analog Ground, Connect to PGND.
When forced high, the device operates in fixed frequency PWM mode. When forced
low, it enables the Power Save Mode with automatic transition from PFM mode to
fixed frequency PWM mode. This pin must be terminated.
Analog Power. Short externally to PVIN.
Supply Voltage. Bypass with a 10μF ceramic capacitor to PGND.
