NCP137数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

NCP137 is a 700 mA LDO equipped with NMOS pass
transistor and a separate bias supply voltage (VBIAS). The device
provides very stable, accurate output voltage with low noise suitable
for space constrained, noise sensitive applications. In order to
optimize performance for battery operated portable applications, the
NCP137 features low IQ consumption. The WLCSP6 1.2 mm x 0.8 mm
package is optimized for use in space constrained applications.

特性 Features

• Ultra-Low Dropout of Typ. 40mV
• Allows to save power and operates with very low Vin-Vout voltage.
• Adjustable Voltage version
• Excellent choice for low voltage Vcore applications
• 40 mV typical dropout at the full 700 mA load.
• minimizes the power loss across the regulator
• Guaranteed Output Current from 0mA to 700mA
• Very good choice for high current applications
• 0.5% Typical Output Voltage Accuracy
• Perfect fit for POL applications
• Output Current in Excess of 700mA
• Output Active Discharge option available

应用 Application

• Battery - powered and Portable Equipment
• Smartphones, Tablets
• Cameras, DVRs, Camcorders

简介

NCP137属于集成电路（IC）的LED驱动器。由制造生产的NCP137LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
