DescripTion
The LT®3501 is a dual-current mode PWM step-down DC/DC converter with two internal 3.5A switches. Inde- pendent 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 xed 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 ef ciency 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-start pin, or by using the SHDN pin the entire part can be placed in a low quiescent current shutdown mode.
The LT3501 is available in a 20-lead TSSOP package with exposed leadframe for low thermal resistance.
