NCV8870_16 Datasheet, PDF (1/15 Pages) ON Semiconductor – Automotive Grade Non-Synchronous Boost Controller

NCV8870
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
