LT3501EFE#TRPBF

LT®3501 is a dual-current mode PWM step-down DC/DC converter with two internal 3.5A switches. The Independent input voltage, feedback, soft-start, and power good pins for each channel simplify complex power supply tracking/sequencing requirements. 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. Programmable frequency allows for optimization between efficiency and external component size. 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. Application includes DSP power supplies, disc drives, DSL/cable modems, wall transformer regulation, and distributed power regulation.

• Two switching regulators with 3A output capability
• Independent supply to each regulator
• Antiphase switching, outputs can be paralleled
• Independent, sequential, ratiometric or absolute tracking between outputs
• Independent soft-start and power good pins
• Enhanced short-circuit protection, low shutdown current <lt/>10µA
• Typical SHDN threshold is 1.28V (VOUT1/2 = 0V, RT/SYNC = 133K, TJ = 25°C)
• Minimum feedback voltage line regulation is -1% (VVIN1/2 = 3V to 25V, TJ = 25°C)
• 20-lead plastic TSSOP package
• Temperature rating range from -40°C to 125°C
