Boost (step-up)
Efficient conversion of an input voltage to a higher output voltage
High efficiency, broad portfolio
Our extensive step-up regulator portfolio includes synchronous and nonsynchronous devices that address applications ranging from milliamps up to 100 A with efficiencies as high as 96%. Our products include key features such as low quiescent current (IQ) for extended battery life, high power density for small-size and spread-spectrum technology for low EMI.
