NCV8853

NCV8853 Automotive Grade Non-Synchronous Buck Controller The NCV8853 is an adjustable−output non−synchronous buck controller which drives an external P−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 internal soft−start, undervoltage lockout, cycle−by−cycle current limit, hiccup−mode overcurrent protection, hiccup−mode short−circuit protection. Additional features include: power good signal, low quiescent current sleep mode and externally synchronizable switching frequency. Features Ultra Low Iq Sleep Mode Adjustable Output with 800 mV ±2.0% Reference Voltage Wide Input of 3.1 to 44 V with Undervoltage Lockout (UVLO) Power Good (PG) Internal Soft−Start (SS) Fixed−Frequency Peak Current Mode Control Internal Slope Compensating Artificial Ramp Internal High−Side PMOS Gate Driver Regulated Gate Driver Current Source External Frequency Synchronization (SYNC) Programmable Cycle−by−Cycle Current Limit (CL) Hiccup Overcurrent Protection (OCP) Output Short Circuit Hiccup Protection (SCP) Space−Saving 8−PIN SOIC Package NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable These Devices are Pb−Free and are RoHS Compliant www.onsemi.com 8 1 SOIC−8 SUFFIX D CASE 751 MARKING DIAGRAM 8 V8853xx ALYW G 1 V8853xx = Sp...
