SN6505BDBVT

Texas Instruments · Power Management - Specialized · SOT-23-6

SN6505BDBVT from Texas Instruments, in a SOT-23-6. 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 D1 output Open drain output of the first power MOSFET switch for center-tapped transformer primary, carrying peak currents up to 2.4 A.
2 VCC power_in Supply pin requiring 2.25 V to 5.5 V input with 4.7 μF or greater low ESR bypass capacitor, with undervoltage lockout at VCC ≤ 2.25 V.
3 D2 output Open drain output of the second power MOSFET switch for center-tapped transformer primary, carrying peak currents up to 2.4 A.
4 GND power_in Ground connected to power MOSFET source via internal sense circuit, requiring connection to low-inductance ground plane.
5 EN input Active high enable input with internal pull-down; when low or floating disables all circuitry; tie to VCC if unused.
6 CLK input External clock input internally pulled to GND; device automatically switches to internal oscillator (160 kHz for SN6505A, 420 kHz for SN6505B) if valid clock absent for 10-25 μs.
