MIKROE-5468, Click Board, Boost 8 Click2/24/2023
Features and Benefits
- Generates Well-Regulated Positive and Negative Outputs
- Low Quiescent Current:
- 20µA in Active Mode (per Converter)
- <1µA in Shutdown Mode
- Operates with VIN as Low as 1.2V
- Low VCESAT Switch: 250mV at 300mA
- Uses Small Surface Mount Components
- High Output Voltage: Up to ±34V
- Tiny 10-Pin MSOP Package
The LT1945 is a dual micropower DC/DC converter in a 10-pin MSOP package. Each converter is designed with a 350mA current limit and an input voltage range of 1.2V to 15V, making the LT1945 ideal for a wide variety of applications. Both converters feature a quiescent current of only 20µA at no load, which further reduces to 0.5µA in shutdown. A current limited, fixed off-time control scheme conserves operating current, resulting in high efficiency over a broad range of load current. The 36V switch allows high voltage outputs up to ±34V to be easily generated without the use of costly transformers. The LT1945’s low off-time of 400ns permits the use of tiny, low profile inductors and capacitors to minimize footprint and cost in space-conscious portable applications.
