水下机器人3D打印机专用DCDC恒流IC
LED升降压恒流驱动IC大功率可外挂MOS
 Description 
The 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 programmable 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 Converting 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 Shutdown 
? MSOP-10 (FD) Package 
Applications 
? GPS, Portable DVD Backlight 
? Desk Light and Room Lighting 
? Industrial Display Backlight
