Description

  • Typical Application for LM3405A 1.6MHz, 1A Constant Current Buck LED Driver with Internal Compensation in, VBOOST derived from VIN through a Shunt Zener Diode (D3) (VIN = 18V, IF = 1A). The LM3405A is a 1A constant current buck LED driver designed to provide a simple, high efficiency solution for driving high power LEDs. With a 0.205-V reference voltage feedback control to minimize power dissipation, an external resistor sets the current as needed for driving various types of LEDs
