LM25011MYX

Texas Instruments · DC-DC Converters · MSOP-10-EP

LM25011MYX from Texas Instruments, in a MSOP-10-EP. 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 VIN power_in Input supply voltage with operating range 6V to 42V and transient capability up to 45V.
2 RT input On-time control input where external resistor from VIN sets buck switch on-time and switching frequency.
3 PGD output Power Good logic output indicating when FB voltage exceeds 95% of 2.51V reference with 3.3% hysteresis, requires external pull-up resistor to voltage less than 7V.
4 SS input Soft-Start input where internal 10µA current source charges external capacitor to 2.51V.
5 SGND power_in Signal Ground for all internal circuitry except current limit sense circuit.
6 FB input Feedback input to regulation comparator with 2.51V internal reference voltage.
7 CSG power_in Current Sense Ground connection for current limit sensing circuit and current sense resistor.
8 CS input Current Sense input connected to current sense resistor and anode of free-wheeling diode.
9 SW output Switching Node output internally connected to buck switch source, connects to external inductor, free-wheeling diode cathode, and bootstrap capacitor.
10 BST power_in Bootstrap capacitor connection for buck switch gate driver, connect 0.1µF capacitor from SW to BST with internal diode charging during off-time.
11 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
