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
