General Description
The AP80SY is a current mode LED driver and boost controller. The PWM DIM input not only drives the load PWM switch, but also enables NDRV switching and error amplifier operation. This feature provides ex-tremely fast, true PWM load switching. External cur-rent sense resistor and slope compensation resistor make it flexible for various applications.
An ISEN pin is used for programming LED current. A high contrast ratio true PWM dimming can be achieved by driving DIM pin with a PWM signal. LED current is proportional to the DIM pin duty.
The AP80SY features extensive protection functions that include OLP, SLP, OCP, OVP and OTP. It is available in a SOP-10 package.

一般的描述
AP80SY领导司机当前模式,提高控制器。PWM的输入不仅驱动负载PWM开关,但也使NDRV转换和误差放大器操作。这个特性提供了极其快,真正的PWM开关负载。外部防渗墙检测电阻和斜坡补偿电阻使其灵活的各种应用程序。
一个ISEN销用于编程LED电流。高对比度真正的PWM调光可以通过驾驶暗销与PWM信号。LED电流正比于暗销的职责。
包括OLP的AP80SY特性广泛的保护功能,二,(OCP,OVP,OTP。它在SOP-10包是可用的。
