What is LTC1267?
This is Dual High Efficiency Synchronous Step-Down Switching Regulators. A switching regulator, also known as a switch-mode power supply, is a type of voltage regulator that uses a switching element. Unlike linear regulators, which adjust the output voltage by using a resistive element to drop the excess voltage, switching regulators work by rapidly switching the input voltage on and off to produce a regulated output voltage. |

Switching regulators are typically more efficient than linear regulators, as they can handle larger voltage changes with less power loss. They are also more compact and lighter, making them ideal for use in portable electronic devices. Additionally, switching regulators are capable of regulating a wider range of voltage levels and can handle higher current loads. Manufacturers : Linear Technology  |
