com FEATURES ■ ■ ■ ■ LT3501 Monolithic Dual Tracking 3A Step-Down Switching Regulator DESCRIPTION The LT®3501 is a dual current mode PWM step-down DC/DC converter with two internal 3.
5A switches.
Independent input voltage, feedback, soft-start and power good pins for each channel simplify complex power supply tracking/sequencing requirements.
Both converters are synchronized to either a common external clock input or a resistor programmable fixed 250kHz to 1.
5MHz internal oscillator.
At all frequencies, a 180° phase relationship between channels is maintained, reducing voltage ripple and component size.
Programmable frequency allows for optimization between efficiency and external component size.
Minimum input-to-output voltage ratios are improved by allowing the switch to stay on through multiple clock cycles, only switching off when the boost capacitor needs recharging, resulting in ~95% maximum duty cycle.
Each output can be independently disabled using its own soft-...
