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.
