4.5V to 32V Input High Current
LED Driver IC For Buck, Buck-Boost Topology |
|
| |
| 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,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. |
