The LT3501IFE#TRA1PBF is a monolithic dual tracking 3A step-down switching regulator manufactured by Analog Devices, Inc. This component integrates two current mode PWM step-down DC/DC converters, each with internal 3.5A switches. It is designed for applications requiring independent control, offering independent input voltage, feedback, soft-start, and power good pins for each channel.
The device operates within a wide input voltage range of 3.1V to 25V. The switching frequency can be adjusted from 250kHz to 1.5MHz, allowing for optimization between efficiency and external component size. It maintains a 180° phase relationship between channels, which helps reduce voltage ripple and component size. The maximum duty cycle is approximately 95%, improving minimum input-to-output voltage ratios.
Each output can be independently disabled, and the entire part can be placed in a low quiescent current shutdown mode (<10µA) using the SHDN pin. The LT3501IFE#TRA1PBF is housed in a 20-lead TSSOP package with an exposed leadframe for enhanced thermal performance. Applications include DSP power supplies, disc drives, DSL/cable modems, wall transformer regulation, and distributed power regulation.
The input voltage range is 3.1V minimum to 25V maximum.
It has two outputs.
Each output can deliver up to 3A typical.
The switching frequency is adjustable from 250kHz to 1.5MHz.
It is a non-synchronous regulator, requiring an external Schottky diode.
The maximum duty cycle is 95%.
It is available in a 20-lead TSSOP package with an exposed leadframe.
