NCP6336

NCP6336 Product Preview Configurable 5.0 A Step Down Converter - Transient Load Helper The NCP6336 is a synchronous buck converter optimized to supply the different sub systems of portable applications powered by one cell Li−Ion or three cell Alkaline/NiCd/NiMH batteries. The device is able to deliver up to 5.0 A, with programmable output voltage from 0.6 V to 1.5 V. It can share the same output rail with another DC−to−DC converter and works as a transient load helper. Operation at a 3 MHz switching frequency allows the use of small components. Synchronous rectification and automatic PWM/PFM transitions improve overall solution efficiency. The NCP6336 is in a space saving, low profile 2.0 x 1.6 mm CSP−20 package. Features Input Voltage Range from 2.3 V to 5.5 V: Battery and 5 V Rail Powered Applications Programmable Output Voltage: 0.6 V to 1.5 V in 10 mV Steps 3 MHz Switching Frequency with On Chip Oscillator Uses 330 nH Inductor and 47 mF Capacitors for Optimized Footprint and Solution Thickness PFM/PWM Operation for Optimum Increased Efficiency Low 35 mA Quiescent Current I2C Control Interface with Interrupt and Dynamic Voltage Scaling Support Enable Pins, Power Good / Fail Signaling Thermal Protections and Temperature Management Transient Load Helper: Share the Same Rail with Another Rail Small 2.0 x 1.6 mm / 0.4 mm Pitch CSP Package These are Pb−Free Devices http://onsemi.com MARKING DIAGRAM WLCSP20 CASE 568AG 6336x AWLYWW G x = P: Prototyp...
