LT3501 - Linear Technology

LT3501 Monolithic Dual Tracking 3A Step-Down Switching Regulator

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 t.

■ 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. Pr.
