Linear Technology LT3431 Manuals

This datasheet introduces LT3431, a high voltage, 3A, 500kHz step-down switching regulator. It features a wide input range (5.5V to 60V), 3A peak switch current, small thermally enhanced 16-pin TSSOP package, constant 500kHz switching frequency, saturated switch design (0.1Ω), peak switch current maintained over full duty cycle range, effective supply current 2.5mA, shutdown current 30µA, 1.2V feedback reference voltage, easily synchronized, cycle-by-cycle current limiting and more.

The LT ®3431 is a 500kHz monolithic buck switching regu- lator that accepts input voltages up to 60V. A high efficiency 3A, 0.1Ω switch is included on the die along with all the nec- essary oscillator, control and logic circuitry.
