CONSONANCE 4.5V to 32V Input, Constant Current Boost HB LED Driver CN5815 General Description: The CN5815 is a current mode fixed-frequency PWM controller for high brightness(HB) LED driving applications. The device operates from an input supply between 4.5V and 32V and provides to drive an external N-channel MOSFET. The CN5815 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. LED current is set by an external resistor. Current mode control provides improved transient response and simplified loop compensation. On-chip soft start reduces the inrush current on power up.
