POWER LOSS (mW) LT8330 Low I Boost/SEPIC/ Q Inverting Converter with 1A, 60V Switch FEATURES DESCRIPTION n 3V to 40V Input Voltage Range The LT 8330 is a current mode DC/DC converter capable n Ultralow Quiescent Current and Low Ripple Burst of generating either positive or negative output voltages Mode Operation: I = 6A using a single feedback pin. It can be configured as a Q n 1A, 60V Power Switch boost, SEPIC or inverting converter consuming as low as n Positive or Negative Output Voltage Programming 6A of quiescent current. Low ripple Burst Mode opera- with a Single Feedback Pin tion maintains high efficiency down to very low output n Fixed 2MHz Switching Frequency currents while keeping the output ripple below 15mV in n Accurate 1.6V EN/UVLO Pin Threshold a typical application. The internally compensated current n Internal Compensation and Soft-Start mode architecture results in stable operation over a wide n Low Profile (1mm) ThinSOT Package range of input and output voltages. Integrated soft-start n Low Profile (0.75mm) 8-Lead (3mm 2mm) DFN and frequency foldback functions are included to control Package inductor current during start-up. The 2MHz operation n AEC-Q100 Qualified for Automotive Applications combined with small package options, enables low cost, area efficient solutions.
