illustrate

The regulators of the LM22670 series are monolithic integrated circuits, buck (buck) switching regulators, capable of driving loads up to 3A with excellent line and load regulation characteristics. The high efficiency (> 90%) is achieved by using a low-resistance N-channel MOSFET. The series consists of a fixed 5V output and an adjustable version.

SIMPLE SWITCHER ® The concept offers an easy-to-use complete design using a minimum number of external components and WEBENCH for national semiconductors ® Design tools. WEBENCH of National Semiconductor ® Tools include features such as external component calculations, electrical simulation, thermal simulation, and simple design, construction, and other boards. The switching clock frequency is made by an internal fixed-frequency oscillator, which is 500 kHz. The switching frequency can also be adjusted by an external resistor or by external clock synchronization up to 1MHz. It can also automatically synchronize multiple regulators to share the same switching frequency. The LM22670 series also features built-in thermal shutdown, current limiting, and enable control inputs that can adjust up and down quiescent current standby with a power as low as 25μA.
