The LT3510 is a dual current mode PWM step-down DC/DC converter with two internal 2.5A switches. It supports a wide input voltage range of 3.1V to 25V and has independent power supply inputs, feedback, soft-start and power good pins.
The LT3510 is a dual‑channel, constant‑frequency, current‑mode step‑down DC‑DC converter that delivers up to 2 A per channel. Each channel has independent input, feedback, soft‑start and power‑good pins, enabling flexible tracking and sequencing of power supplies.
The datasheet details absolute maximum ratings, electrical characteristics such as a 3.1 V‑25 V input range, 250 kHz‑1.5 MHz switching frequency, ~95 % maximum duty cycle, and includes pin configurations, typical performance graphs, and ordering information for the 20‑lead TSSOP package with exposed leadframe.

The absolute maximum rating for VIN1/2 is 25 V.
In shutdown mode it typically draws 9 µA from VIN1.
It is supplied in a 20‑lead TSSOP package with an exposed leadframe.
The device can operate from 250 kHz up to 1.5 MHz.
