General Description
The EMD2794/EMD2795 is a 1.5x/1.0x charge pump that provides four regulated current sources.
It accepts an input voltage range from 2.7V to 5.5V and maintains a constant current determined by an external resistor.
Key Features
- es.
- Regulated current sources with ±0.5% matching High efficiency 3/2 boost function Drives one to four white LEDs. 2.7V to 5.5V input range Up to 80mA output current Analog brightness control frequency is fixed at 1.2MHz to make noise filtering easier. Brightness control can be done by both linear and PWM techniques. Linear control is achieved by applying 0V to 3.0V to the BRGT pin to linearly vary the LED current. PWM Active-low or high shutdown input (‘94/95) Very small solution.
