ON Semiconductor LED boost converter

NCP5010 is a constant current application of fixed frequency PWM, integrated rectification function, products with small size, minimal external components, providing up to 500mW output power, 2-5 can drive a series of white LED. A single resistor sets the LED current and can also be configured with a fixed output voltage boost converter for the OLED bias device which can be configured to output voltage 20V. When the device is in standby mode, it includes a real circuit to disconnect the load from the battery. It also has over voltage protection and short circuit protection. NCP5010 features a flip chip 1.7x1.7mm package. Optimized for use with inductors and ceramic capacitors. Available in small white LED color LCD display background lighting, mobile phone, digital camera, MP3 player and high step-up converter NCP5010 features: input voltage 2.7V-5.5V efficiency as high as 84% with low noise attenuation switch 1MHz PWM DC/DC converter off current 1uA 8 pin 1.7x1.7mm flip chip package.
