Automotive Grade
Non-Synchronous Boost
Controller
The NCV8870 is an adjustable output non−synchronous 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, hiccup−mode short−circuit
protection and thermal shutdown.
Additional features include low quiescent current sleep mode and
externally−synchronizable switching frequency.
Features
• Peak Current Mode Control with Internal Slope Compensation
• 1.2 V ±2% Reference voltage
• Fixed Frequency Operation
• Wide Input Voltage Range of 3.2 V to 40 Vdc, 45 V Load Dump
• Input Undervoltage Lockout (UVLO)
• Internal Soft−Start
• Low Quiescent Current in Sleep Mode
• Cycle−by−Cycle Current Limit Protection
• Hiccup−Mode Overcurrent Protection (OCP)
• Hiccup−Mode Short−Circuit Protection (SCP)
• Thermal Shutdown (TSD)
• This is a Pb−Free Device
