DC-DC大功率升降压恒流IC可PWM调光无频闪LED专用AP5503 60V DC / DC大功率升降压恒流驱动器描述AP5503是一款电流模式DC / DC升降压恒流驱动器，具有用于驱动LED的外部功率NMOS。 AP5503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。在500KHz的工作频率下，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。AP5503采用MSOP-10（FD）封装。特征高电压：VIN高达60V，VOUT高达60V降压，升压或降压 - 升压操作具有500KHz和200KHz开关频率的电流模式PWM简单的调光：通过一个外部电容将模拟，PWM或PWM转换成模拟信号软启动以避免浪涌电流可编程过电压保护可限制输出电压VIN欠压闭锁和热关断MSOP-10（FD）包装

AP5503 60V DC/DC Buck-Boost Configuration ConverterDescriptionThe AP5503 is a current mode DC/DC converter with outside power NMOS designed to drive LEDs. The AP5503 operates as a LED driver in buck, boost and buck-boost mode. The LED current is externally pro-grammable with a 120mV sense resistor. With a 500KHz operating frequency, the external inductor and input/output capacitors can all be small. Dimming can be either analog, PWM, or PWM converting to analog with an external capacitor.The AP5503 is available in MSOP-10 (FD) package.Features„High Voltage : VIN up to 60V, VOUT up to 60V„Buck, Boost or Buck-Boost Operation„Current Mode PWM with 500KHz and 200KHz Switching Frequency„Easy dimming : Analog, PWM or PWM Con-verting to Analog with One External Capacitor„Soft Start to Avoid Inrush Current„;Programmable Over Voltage Protection to Limit Output Voltage„VIN Under Voltage Lockout and Thermal Shut-down„MSOP-10 (FD) Package系曾生：13410492646 Q Q:3004825478可提供IC测试板和配套方案
