LM2670S-5.0
Overview
The LM2670 series of regulators are monolithic integrated circuits which provide all of the active functions for a step-down (buck) switching regulator capable of driving up to 3-A loads with excellent line and load regulation characteristics. High efficiency (>90%) is obtained through the use of a low ONresistance DMOS power switch.
- 1 Efficiency Up to 94%
- Simple and Easy to Design With (Using Off-the- Shelf External Components)
- 150-mΩ DMOS Output Switch
- 3.3-V, 5-V, 12-V Fixed Output and Adjustable (1.2 V to 37 V) Versions
- 50-µA Standby Current When Switched OFF
- ±2% Maximum Output Tolerance Over Full Line and Load Conditions
- Wide Input Voltage Range: 8 V to 40 V
- External Sync Clock Capability (280 kHz to 400 kHz)
- 260-kHz Fixed Frequency Internal Oscillator
- -40 to 125°C Operating Junction Temperature Range
