General Description:

The CN5816 is a current mode fixed-frequency PWM controller for high current LED applications. The device operates from an input supply between 4.5V and 32V and provides to drive an external N-channel MOSFET. With the maximum operating input voltage of 32V, the CN5816 is ideal for buck or buck-boost LED driver operation.

The CN5816 contains all the necessary building blocks including a bandgap reference, a 330KHz oscillator, current-mode control circuitry, chip shutdown block, softstart block and gate driver, etc.

Current mode control provides improved transient response and simplified loop compensation. On-chip soft start reduces the inrush current on power up. The other features include chip shutdown, over voltage protection, built-in 5V regulator and slope compensation, etc.

The CN5816 is available in 10-pin SSOP package.
