A7330

DC-DC CONVERTER BUCK (STEP-DOWN)

SENSORLESS CC/CV

AiT Semiconductor Inc.

DESCRIPTION

FEATURES

A7330 is a wide input voltage, high efficiency

step-down DC/DC converter that operates in either

CV (Constant Output Voltage) mode or CC(Constant

Output Current) mode. A7330 provides up to 3.5A

output current at 125kHz switching frequency.

A7330 integrates control scheme to achieve

high-accuracy constant current control without the

expensive, high accuracy current sense resistor. It

also integrates adaptive gate drive to achieve

excellent EMI performance passing EN55022 Class

B EMC standard without adding additional EMI

components while maintaining high conversion

efficiency.



Up to 3.5A output current

125kHz Switching Frequency Eases EMI Design

91% Efficiency (V_OUT=5V@2.4A at V_IN=12V)

Resistor Programmable for Output Cable Drop

Compensation



Cycle-by-Cycle Current Limit, Output Over

Voltage Protect, Thermal Shutdown, Input Under

Voltage Lockout



Integrated Soft Start

±7.5% CC Accuracy

±2% CV Accuracy

High-Side R_DSON50mΩ

Available in PSOP8 Package

Protection features include cycle-by-cycle current

limit, thermal shutdown, and frequency foldback at

short circuit.
