NCV91300

Configurable 3.0 A PWM Step Down Converter NCV91300 The NCV91300 is a synchronous PWM buck converter optimized to supply the different sub systems of automotive applications post regulation system from 2.0 V up to 5 V input. The device is able to deliver up to 3.0 A, with programmable output voltage from 0.6 V to 3.3 V. Operation at up to 2.15 MHz switching frequency allows the use of small components. Synchronous rectification and automatic PFM−PWM transitions improve overall solution efficiency. The NCV91300 is housed in low profile 3.0 x 3.0 mm QFNW−16 package. Features Power Input Voltage Range from 1.9 V to 5.5 V Analog Input Voltage Range from 3.0 V to 5.5 V Power Capability: 3.0 A at TA = 105°C (RqJA = 40°C/W) Programmable Output Voltage: 0.6 V to 3.3 V in 5 mV, 10 mV and 20 mV Steps Up to 2.15 MHz Switching Frequency with On Chip Oscillator Spread Spectrum or Sync Input Pin for EMI Optimization Uses 1.0 mH Inductor and at Least 20 mF Capacitors for Optimized Footprint and Solution Thickness PFM/PWM Operation for Optimum Efficiency Low 65 mA Quiescent Current I2C Control Interface with Interrupt and Dynamic Voltage Scaling Support Enable Pin, Power Good / Interrupt Signaling Thermal Protections and Temperature Management 3.0 x 3.0 mm / 0.5 mm pitch QFN 16 package These are Pb−Free Devices Typical Applications Automotive Point Of Load (POL) Automotive Telematics Clusters – Camera Automotive Infotainment − Instrumentation Automotive A...
