The LT3508 is a dual current mode PWM step-down DC/DC converter with internal power switches capable of generating two 1.4A outputs.
The LT3508 is a dual‑channel, constant‑frequency, current‑mode step‑down DC/DC converter. It accepts a wide input voltage range of 3.7 V to 36 V and provides two independent 1.4 A output regulators that can be synchronized and operated in opposite phase to reduce input ripple.
The document includes pin configurations, absolute maximum ratings, electrical characteristics, operation details, programming of the switching frequency, and typical application circuits. It also lists recommended inductor selections and performance graphs such as efficiency versus load.
| Input voltage range | 3.7 V to 36 V |
|---|---|
| Efficiency (typical) | 70 %–95 % depending on load |
The LT3508 operates with an input voltage from 3.7 V up to 36 V.
By connecting a resistor from the RT/SYNC pin to ground or by driving the pin with a logic‑level SYNC signal; resistor values are listed in a table.
