A7330
DC-DC CONVERTER BUCK (STEP-DOWN) SENSORLESS CC/CV
DESCRIPTION
FEATURES
A7330 is a wide input voltage, high efficiency Up to 3.1A output current
step-down DC/DC converter that operates in either 125kHz Switching Frequency Eases EMI Design
CV (Constant Output Voltage) mode or CC (Constant 91% Efficiency (VOUT=5V@2.4A at VIN=12V)
Output Current) mode. A7330 provides up to 3.1A Resistor Programmable for Output Cable Drop
output current at 125kHz switching frequency.
Compensation
A7330 integrates control scheme to achieve Cycle-by-Cycle Current Limit, Input Over Voltage
high-accuracy constant current control without the
Protect, Thermal Shutdown, Input Under Voltage
expensive, high accuracy current sense resistor.
