DIOO · DC-DC Converters · TSOT-23-6

DIO6970TST6 from DIOO, in a TSOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Power ground return. Connect to the ground plane with a low-impedance path; input capacitor CIN loop area to this pin must be minimized.
2 SW power_out Switching node. Connect to the output inductor. This is the common node between the internal high-side and low-side MOSFETs; keep the PCB copper area minimized to reduce noise.
3 VIN power_in Power input, 4.5V to 24V (28V abs max). Bypass to GND with a low-ESR ceramic capacitor (≥4.7µF X5R) placed close to the pin.
4 FB input Output feedback pin. Connect to the center tap of the output resistor divider to program VOUT = 0.8V × (1 + R1/R2). Internal reference is 0.8V typical (0.788-0.812V). Optional 10-47pF feed-forward cap in parallel with R1 speeds up transient response.
5 EN input Enable control input. Pull high (VENH ≥ 1.5V) to enable the regulator; pull low (VENL ≤ 0.4V) to shut down. Do not float. Add a 1MΩ pull-down to GND if driven from a high-impedance source connected to a battery rail.
6 BS passive Bootstrap pin for the high-side switch gate driver. Connect a 100nF (0.1µF) low-ESR ceramic capacitor between BS and SW to form a floating supply. Absolute max is SW+6V.

Provenance

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

  • Datasheet: DIOO datasheet (10 pp, sha256 a799748e790264ad, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
