TD8002ES5X

Shenzhen JingYang · DC-DC Converters · SOT-23-5

TD8002ES5X from Shenzhen JingYang, in a SOT-23-5. 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 EN input Enable control input. Pull high (VIH ≥ 1.5V) to turn the IC on; pull low (VIL ≤ 0.4V) to disable the IC. Must not be left floating.
2 GND power_in Ground reference pin for the device.
3 LX output Power switching output. Connect an external inductor to the drains of the internal high-side PMOS and low-side NMOS. Switches between VIN and GND at ~1MHz.
4 VIN power_in Power supply input pin. Drive with 2.5V to 5.5V to power the chip. Bypass with a 10µF MLCC to GND close to the pin.
5 FB input Voltage feedback input. Connect FB to VOUT through a resistor divider; the IC regulates FB to the internal 0.6V reference (VREF = 0.588-0.612V). VOUT = 0.6V × (1 + R1/R2).
