LT3970EMS#TRPBF

Analog Devices · DC-DC Converters · MSOP-10

LT3970EMS#TRPBF from Analog Devices, in a MSOP-10. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 FB input Feedback pin regulated to 1.21V; connect the feedback resistor divider tap here (LT3970 adjustable version).
2 EN input Shutdown when low and active when high, with a 1V rising and 0.97V falling hysteretic threshold; tie to VIN if unused, and ground it if VIN is below 4.2V.
3 VIN power_in Supplies current to the internal circuitry and the internal power switch; must be locally bypassed.
4 GND power_in Ground pin that must be soldered to the PCB.
5 GND power_in Ground pin that must be soldered to the PCB.
6 SW output Output of the internal power switch; connect to the inductor.
7 BOOST passive Provides a drive voltage higher than the input voltage to the internal bipolar NPN power switch.
8 BD input Anode of the boost diode, which also supplies current to the internal regulator when BD is above 3.2V.
9 PG output Open-drain output of an internal comparator that stays low until FB is within 10% of final regulation; valid when VIN is above 4.2V and EN is high.
10 RT passive A resistor tied between RT and ground sets the switching frequency.

CAD (KiCad official)

  • Symbol: LT3970EMS#TRPBF
  • Footprint: Package_SO:MSOP-10_3x3mm_P0.5mm
  • 3D model: MSOP-10 (KiCad packages3D, STEP)
  • 3D model files: lt3970ems-trpbf-etched.step / lt3970ems-trpbf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lt3970ems-trpbf.step / lt3970ems-trpbf.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Analog Devices datasheet (24 pp, sha256 e25978555387c0ba, retrieved 2026-10-30, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
