The NCP6343 is a synchronous buck converter optimized to supply recent micro processors (ARM core processor, GPU), memories, that demand high power at low voltages of portable applications powered by one cell Li-ion or three cell Alkaline/NiCd/NiMH batteries.
The device is able to deliver up to 3.0 A, with programmable output voltage from 0.6 V to 1.4 V. It could share the same output rail with another DCDC/LDO 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 NCP6343 is in a space saving, low profile 1.99 x 1.34 mm CSP-15 package.
2.3 V to 5.5 V Input Voltage Range - Support Latest Battery
3 MHz Switching Frequency - Reduced output inductor and capacitor size
DVS support through I2C - Optimizes processor power
Enabling with pins or I2C - Flexible enabling and disabling
IC access in off mode - Pre programming at low power
Transient Load Helper - Share the same output rail with another DCDC/LDO without sinking current on shared rail
