LM2750 Overview
Description
The LM2750 is a switched-capacitor doubler that produces a low-noise, well regulated, 5.0V output. It can supply up to 120mA of output current over a 2.9V to 5.6V input range, as well as up to 40mA of output current when the input voltage is as low as 2.7V.
Key Features
- Low Noise, 5.0V ± 4% Regulated Output n 85% Peak Efficiency 70% Average Efficiency over Li-Ion Input Range (2.9V-to-4.2V)
- Output Current up to 120mA with 2.9V ≤ VIN ≤ 5.6V Output Current up to 40mA with 2.7V ≤ VIN ≤ 2.9V
- Wide Input Voltage Range: 2.7V to 5.6V
- Fixed 1.7MHz switching frequency for a low-noise, low-ripple output signal
- Pre-regulation minimizes input current ripple, keeping the battery line (VIN) virtually noise-free
- Tiny LLP package with out
