LT1947
Key Features
- The device contains two independent switching regulators
- The main regulator has an adjustable output voltage with an internal 1.1A switch that can generate a boosted voltage as high as 30V
- The second regulator’s output is also adjustable up to 30V and can deliver 10mA for positive bias
- A simple level-shift charge pump off the main switch node generates the negative bias voltage
- An external capacitor sets the delay time from AVDD’s final value to the rising edge at the VON pin
- The device operates from an input range of 2.7V to 8V and is available in a 10-lead MSOP package
- LTC and LT are registered trademarks of Linear Technology Corporation
- 6V SW1, SW2 Voltage
- 36V VON, VO2 Voltage
- 8V Operating Temperature Range (Note 2)
