LM3409QHVMY

Texas Instruments · LED Drivers · HVSSOP-10-EP-0.5mm

LM3409QHVMY from Texas Instruments, in a HVSSOP-10-EP-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 UVLO input Input undervoltage lockout connects to a resistor divider from VIN and GND, with a turn-on threshold of 1.24 V and turnoff hysteresis provided by a 22 µA current source.
2 IADJ input Analog LED current adjust accepts a voltage from 0 to 1.24 V, or a resistor to GND, or can be left open to set the current sense threshold voltage.
3 EN input Logic level enable and PWM dimming input: a voltage above 1.74 V enables the device, and a voltage below 0.5 V gives low-power shutdown.
4 COFF input Off-time programming pin: a resistor from VO and a capacitor to GND set the off-time.
5 GND power_in Connect to system ground.
6 PGATE output Gate drive output connects to the gate of the external P-channel MOSFET, with a 2-Ω, 1-A peak gate drive.
7 CSN input Negative current sense connects to the negative side of the sense resistor.
8 CSP input Positive current sense connects to the positive side of the sense resistor and also to VIN.
9 VCC power_out VIN-referenced linear regulator output connects to VIN through at least a 1-µF ceramic capacitor and powers the P-channel MOSFET drive.
10 VIN power_in Input voltage connects to the input supply, with a VIN range of 6 V to 75 V for the LM3409HV-Q1 variant.
11 DAP passive Exposed pad (from the footprint; not named in the datasheet pin table).
