2 MHz Non-Synchronous SEPIC/Boost Controller
NCV898031
The NCV898031 is an adjustable output non−synchronous 2 MHz SEPIC/boost controller which drives an external N−channel MOSFET. The device uses peak current mode control with internal slope compensation. The IC incorporates an internal regulator that supplies charge to the gate driver.
Protection features include internally−set soft−start, undervoltage lockout, cycle−by−cycle current limiting and thermal shutdown.
Additional features include low quiescent current sleep mode and microprocessor compatible enable pin.
Features
• Peak Current Mode Control with Internal Slope Compensation • 1.2 V $2% Reference Voltage • 2 MHz Fixed Frequency Operation • Wide Input Voltage Range of 3.
