NCV8873
Automotive Grade
Non-Synchronous Boost
Controller
The NCV8873 is an adjustable output nonâsynchronous 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
externallyâsynchronizable switching frequency.
Features
⢠Peak Current Mode Control with Internal Slope Compensation
⢠0.2 V $3% Reference Voltage for Constant Current Loads
⢠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
⢠CycleâbyâCycle Current Limit Protection
⢠HiccupâMode Overcurrent Protection (OCP)
⢠Thermal Shutdown (TSD)
⢠This is a PbâFree Device
