peculiarity

Wide input voltage range: 4.5V to 42V Internally compensated voltage mode control Stable and low ESR ceramic capacitors 200mΩ N-channel MOSFETs Output Voltage Options:

- ADJ (e.g. 1.285V low output) Feedback reference accuracy± 1.5% The switching frequency is adjustable between 500 kHz

200 kHz and 1 MHz -40°C to 125°C operating junction temperature range Precision enable pins Integrated starter diode Adjustable soft start Full WEBENCH ® enabled Buck and reversed-phase buck-boost applications LM22680Q is automotive-grade and AEC - Q100 qualified (-40°C to +125°C operating junction temperature)

illustrate

The LM22680 series of regulators are monolithic integrated circuits that enable step-down (buck) switching regulators to drive loads up to 2A with excellent line and load regulation characteristics. The high efficiency (> 90%) is achieved by using a low-resistance N-channel MOSFET.

The SIMPLE SWITCHER ® concept provides an easy-to-use complete design with minimal number of external components and National Semiconductor's WEBENCH ® design tools. National Semiconductor's WEBENCH ® tools include features such as external component calculations, electrical simulation, thermal simulation, and simple design, build, 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. LM22680 series also features built-in thermal shutdown, current limiting, and enable control inputs that can adjust up and down quiescent current standby status with a low power of 25μA. An adjustable soft-start function is by selecting the appropriate external soft-start capacitor.
