NCV898031
2 MHz Non-Synchronous
SEPIC/Boost Controller
The NCV898031 is an adjustable output nonâsynchronous 2 MHz
SEPIC/boost controller which drives an external Nâchannel
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 internallyâset softâstart, undervoltage
lockout, cycleâbyâcycle 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 3.2 V to 40 V, 45 V Load Dump
⢠Input Undervoltage Lockout (UVLO)
⢠Internal SoftâStart
⢠Low Quiescent Current in Sleep Mode (< 10 mA Typical)
⢠CycleâbyâCycle Current Limit Protection
⢠HiccupâMode Overcurrent Protection (OCP)
⢠HiccupâMode ShortâCircuit Protection (SCP)
⢠Thermal Shutdown (TSD)
⢠This is a PbâFree Device
Typical Applications
⢠Small Form Factor PointâofâLoad Power Regulation
⢠Headlamps
⢠Backlighting
