Linear Technology introduces another monolithic buck switching regulator LT3972 with an adjustable frequency from 200kHz to 2.4MHz .
LT3972 operates over an input voltage range from 3.6 to 33 volts and offer a maximum output current of 3.5A .
Like LT3680 and other buck switching regulators the LT3972 offers output foltage from 0.79V to 30 V , thermal protection , soft start capability and many other features .
The design circuit of the LT3972 circuit is almost the same like LT3980 .
To design the application circuit you need to calculate few components values .
The LT3972 like other monolithic buck regulators manufactured by Linear Technology are ideal for low cost applications .
