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 oscill.

Monolithic Dual Tracking 3A Step-Down Switching Regulator

www.DataSheet4U.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-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. , LT, LTC, and LTM are registered trademarks of Linear Technology Corporation.
