LM3630ATMX规格书详情
LM3630ATMX属于集成电路(IC)的LED驱动器。由美国德州仪器公司制造生产的LM3630ATMXLED 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。

3 Description
The LM3630A is a current-mode boost converter
which supplies the power and controls the current in up to two strings of 10 LEDs per string. Programming
is done over an I2C-compatible interface. The
maximum LED current is adjustable from 5 mA to
28.5 mA. At any given maximum LED current the
LED brightness is further adjusted with 256 exponential or linear dimming steps. Additionally,
pulsed width modulation (PWM) brightness control
can be enabled allowing for LED current adjustment
by a logic level PWM signal.
The boost switching frequency is programmable at
500 kHz for low switching loss performance or 1 MHz
to allow the use of tiny low-profile inductors. A setting for a 10% offset of these frequencies is available.
Overvoltage protection is programmable at 16 V,
24 V, 32 V, or 40 V to accommodate a wide variety of
LED configurations and Schottky diode/output
capacitor combinations.
The device operates over a 2.3-V to 5.5-V operating
voltage range and –40°C to +85°C ambient
temperature range. The LM3630A is available in an ultra-small 12-bump DSBGA package.
