LM3370
Description
The LM3370 is a dual step-down DC-DC converter optimized for powering ultra-low voltage circuits from a single Li-Ion battery and input rail ranging from 2.7V to 5.5V. It provides two outputs with 600mA load per channel.
Key Features
- 600mA Load Per Channel
- 2MHz PWM Fixed Switching Frequency (Typ.)
- The Bucks Operate 180° Out-of-Phase Timing Offset for Noise and Input Surge Current Abatement
- Internal Synchronous Rectification for High Efficiency
- Internal Soft Start
- Power-on-Reset Function for Both Outputs
- 2.7V ≤ VIN ≤ 5.5V
- Operates from a Single Li-Ion Cell or 3 Cell NiMH/NiCd Batteries and 3.3V/5.5V Fixed Rails
- 2.2µH Inductor, 4.7µF Input and 10µF Output Capacitor Per Channel
- 16-lead WSON Package (4 mm x 5 mm x 0.8 mm)
