LM3409 - PFET Buck Controller
The LM3409/09HV are P-channel MosFET (PFET) controllers for step-down (buck) current regulators.
They offer wide input voltage range, high-side differential current sense with low adjustable threshold voltage, fast output enable/disable function and a thermally enhanced eMSOP-10 package.
These featu
LM3409 Features
* combine to make the LM3409/09HV ideal for use as constant current sources for driving LEDs where forward currents up to 5A are easily achievable. The LM3409/09HV uses Constant Off-Time (COFT) control to regulate an accurate constant current without the need for external control loop compensation. An
