UC2573D

Texas Instruments · DC-DC Converters · SOIC-8

UC2573D from Texas Instruments, in a SOIC-8. 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 EAINV input Error amplifier inverting input, regulated to 1.5V and rated -0.6V to VCC; also feeds the sleep comparator (2.2V threshold).
2 EAOUT output Error amplifier output to the PWM comparator, with maximum 25mA current rating.
3 CS input Current sense comparator input for pulse-by-pulse current limit, threshold 0.43V below VCC and rated -0.3V to VCC.
4 VCC power_in Positive supply input, absolute maximum 35V, with undervoltage lockout start threshold of 4.2V typical.
5 OUT output Gate drive output (0.5A peak) for the external PMOS switch, rated -0.7A to 0.7A.
6 GND power_in Ground reference for the device.
7 RAMP input Oscillator ramp input to the PWM comparator, rated -0.3V to 4V.
8 3VREF power_out 3V reference output (2.94V to 3.06V), sourcing up to 15mA absolute maximum.
