LTC3616 - Step-Down DC/DC Converter

Description

The LTC®3616 is a low quiescent current monolithic synchronous buck regulator using a current mode, constant frequency architecture.

The no-load DC supply current in sleep mode is only 70µA while maintaining the output voltage (Burst Mode operation) at no load, dropping to zero current in shutdown.

Features

  • n 6A Output Current n 2.25V to 5.5V Input Voltage Range n Low Output Ripple Burst Mode® Operation: IQ = 75µA n ±1% Output Voltage Accuracy n Output Voltage Down to 0.6V n High Efficiency: Up to 95% n Low Dropout Operation: 100% Duty Cycle n Programmable Slew Rate on SW Node Reduces Noise and EMI n Adjustable Switching Frequency: Up to 4MHz n Optional Active Voltage Positioning (AVP) with Internal Compensation n Selectable Pulse-Skipping/Forced Continuous/Burst Mode Operation with Adjustable Burs.
