NCV898031
2 MHz Non-Synchronous
SEPIC/Boost Controller
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 3.2 V to 40 V, 45 V Load Dump
• Input Undervoltage Lockout (UVLO)
• Internal Soft−Start
• Low Quiescent Current in Sleep Mode (< 10 mA Typical)
• Cycle−by−Cycle Current Limit Protection
• Hiccup−Mode Overcurrent Protection (OCP)
• Hiccup−Mode Short−Circuit Protection (SCP)
• Thermal Shutdown (TSD)
• NCV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q100
Qualified and PPAP Capable
• This is a Pb−Free Device
Typical Applications
• Small Form Factor Point−of−Load Power Regulation
• Headlamps
• Backlighting
