TD1836

Techcode Semicon · DC-DC Converters · SOT-23-6

TD1836 from Techcode Semicon, 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 BST power_out Bootstrap pin: a capacitor connected between SW and BS forms a floating supply that drives the power switch gate above the supply voltage, with BS to GND rated VSW - 0.3 V to VSW + 6 V.
2 GND power_in Ground and voltage reference for the regulated output, which requires special layout so this node is isolated from the D1 to C1 ground path to prevent switching current spikes from inducing noise.
3 FB input Feedback input that sets the output voltage through an external resistor divider to GND, and the frequency foldback comparator lowers the oscillator frequency when FB is below 300mV to prevent current-limit runaway during a short circuit.
4 EN input On/off input that must be pulled above 1.35V (EN rising threshold) to turn the device on, and can be connected to VIN through a 1MΩ resistor for automatic enable.
5 VIN power_in Supply input that operates from an 11V to 75V unregulated input per the pin description, requires C1 to prevent large input voltage spikes, and is rated -0.3 V to 80 V absolute maximum.
6 SW output Power switching output that is the drain of the internal N-channel power MOSFET supplying the output LC filter, with SW to GND rated -0.3 V to VIN + 0.3 V.
