产品概述 返回TOPHvX嘉泰姆
The CXLE8158 is a high efficiency charge pump white
LED driver; the device drives up four white LEDs with
regulated constant current for uniform intensity. The supply
voltage ranges from 2.7V to 5.5V and it is optimized for
a Li-ion battery application. The CXLE8158 operates in 1x,
1.5x, and 2x charge pump modes and automatically
switches the charge pump modes depend on the input
voltage to maintain the required power for high power
efficiency. The CXLE8158 provides up to 30mA per LED
for a total of 120mA and allows several methods, such as
a PWM signal on the CTRL0 pin for LED dimming. Three
control logic pins allow to disable or enable a combination
of LEDs. The supply current is only 2mA in 2x mode,
and the EN pin allows the device to enter shutdown mode
with 2mA quiescent current. The CXLE8158 switches at
1MHz frequency and only requires four 1mF ceramic capacitors
and one resistor, and ensures low input current
ripple and EMI.
The CXLE8158 is available in a 16-pin QFN package.
