AP5502 60V DC / DC升降压恒流驱动器

描述

AP5502是一款电流模式DC / DC升降压恒流驱动器，内置2.5A，60V开关，专门用于驱动LED。 AP5502在降压，升压和降压 - 升压模式下用作LED驱动器。 LED电流采用120mV检测电阻进行外部编程。采用200KHz（SOP-8（FD））/ 500KHz（TDFN3X3-10）工作频率时，外部电感和输入/输出电容都可以很小。调光可以是模拟，PWM或PWM转换为模拟与外部电容器。

AP5502采用SOP-8（FD），TSSOP-14（FD）和TDFN3X3-10封装。

Description

The AP5502 is a current mode DC/DC converter with an internal 2.5A, 60V switch specifically designed to drive LEDs. The AP5502 operates as a LED driver in buck, boost and buck-boost mode. The LED current is externally programmable with a 120mV sense resistor. With a 200KHz (SOP-8 (FD)) /500KHz (TDFN3X3-10) operating frequency, the external inductor and in-put/output capacitors can all be small. Dimming can be either analog, PWM, or PWM converting to analog with an external capacitor.

The AP5502 is available in SOP-8 (FD), TSSOP-14 (FD) & TDFN3X3-10 package.
