LM2630 is Synchronous Step-Down Power Supply Controller manufactured by National Semiconductor.
| Part Number | Description |
|---|---|
| LM2631 | Synchronous Step-Down Power Supply Controller |
| LM2633 | Advanced Two-Phase Synchronous Triple Regulator Controller |
| LM2635 | 5-Bit Programmable Synchronous Buck Regulator Controller |
| LM2636 | 5-Bit Programmable Synchronous Buck Regulator Controller |
| LM2637 | Motherboard Power-Supply Solution |
The LM2630 controller provides all the active functions for step-down (buck) switching converters. These dc-to-dc converters provide core CPU power in battery-operated systems. High efficiency is achieved by using synchronous rectification and pulse-skipping mode operation at light load.
