LM25010MH

Texas Instruments · DC-DC Converters · HTSSOP-14-EP

LM25010MH from Texas Instruments, in a HTSSOP-14-EP. 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 NC unconnected No internal connection; may be connected to ground plane for heat dissipation.
2 SW output Switching node connected to buck switch source; internally driven, voltage rating -1.5V to 45V relative to RTN.
3 BST input Bootstrap pin for gate driver capacitor; connects 0.022µF capacitor from SW, charged from VCC during OFF-time; maximum 59V to RTN, 14V to VCC.
4 ISEN input Current sense input; inductor current flows out during OFF-time through 130mΩ internal sense resistor; threshold 1.25A typical (1.0A to 1.5A range).
5 SGND power_in Current sense ground return; recirculating current flows into this pin to the current sense resistor; maximum ±0.3V relative to RTN.
6 RTN power_in Reference ground return for all internal circuitry except the current sense resistor; baseline for absolute voltage ratings.
7 NC unconnected No internal connection; may be connected to ground plane for heat dissipation.
8 NC unconnected No internal connection; may be connected to ground plane for heat dissipation.
9 FB input Feedback voltage input from regulated output; compared to 2.5V ±2% regulation reference and 2.9V overvoltage threshold; input bias current <1nA.
10 SS input Soft start capacitor pin; charged by internal 11.5µA current source to 2.5V during startup; voltage rating 4V maximum to RTN.
11 RON/SD input ON-time control resistor input and shutdown pin; external resistor from VIN sets ON-time; grounding disables regulator with 0.7V threshold and 40mV hysteresis.
12 VCC power_in Bias regulator output; 6.6V to 7.4V for VIN ≥ 8.9V, tracks VIN ±100mV for VIN < 8.9V; absolute maximum 14V to RTN.
13 VIN power_in Input supply voltage; operating range 6V to 42V nominal; absolute maximum 45V to RTN; input bypass capacitors required.
14 NC unconnected No internal connection; may be connected to ground plane for heat dissipation.
15 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
