LM5033MMX

Texas Instruments · DC-DC Converters · VSSOP-10-0.5mm

LM5033MMX from Texas Instruments, in a VSSOP-10-0.5mm. 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 VIN power_in Input to the start-up regulator with an input range of 15 V to 90 V and transient capability to 100 V.
2 REF output Sink-only output that requires an external pullup resistor and can serve as a 2.5-V precision output reference for external circuitry.
3 COMP input Feedback to the inverting input of the PWM comparator through a 3:1 divider, where duty cycle increases as the voltage rises and an internal 5-kΩ pullup goes to 5.2 V.
4 VCC power_in 9.6-V output from the internal high-voltage series pass regulator, which can be overdriven by an external 10 V to 15 V to shut down the internal regulator, with an internal diode connecting VCC to VIN.
5 OUT1 output Alternating output gate driver that can source and sink 1.5 A.
6 OUT2 output Alternating output gate driver that can source and sink 1.5 A.
7 GND power_in Ground connection, where external ground connections must be made with care for optimum performance.
8 CS input Current-sense input for current limit detection; if the voltage exceeds 0.5 V the outputs are disabled and the SS pin is discharged to ground.
9 RT/SYNC input Oscillator timing resistor pin, where an external resistor to ground sets the frequency, that also accepts AC-coupled synchronization pulses from an external source.
10 SS input Soft-start pin with an internal 10-µA current source and external capacitor setting the soft-start timing, which can be pulled below 0.5 V to disable the output drivers.
