LM2750 Overview
The LM2750 is a regulated switched-capacitor doubler that produces a low-noise output voltage. The 5-V output voltage option (LM2750-5.0) can supply up to 120 mA of output current over a 2.9-V to 5.6-V input range, as well as up to 40 mA of output current when the input voltage is as low as 2.7 V. An adjustable output voltage option with similar output current capabilities is also available (LM2750-ADJ).
LM2750 Key Features
- 1 Wide Input Voltage Range: 2.7 V to 5.6 V
- Inductorless Solution: Application Requires Only
- Fixed 5-V Output and Adjustable Output Voltage
- 85% Peak Efficiency
- 70% Average Efficiency Over Li-Ion Input Range (2.9 V to 4.2 V)
- Output Current up to 120 mA With 2.9 V ≤ VIN ≤ 5.6 V
- Output Current up to 40 mA With 2.7 V ≤ VIN ≤ 2.9 V
- Fixed 1.7-MHz Switching Frequency for a LowNoise, Low-Ripple Output Signal
- Pre-Regulation Minimizes Input Current Ripple, Keeping the Battery Line (VIN) Virtually Noise-Free
- Shutdown Supply Current Less Than 2 µA
