CM3728 2.5G/3G CELLULAR PHONE BUCK REGULATOR GENERAL DESCRIPTION FEATURES The CM3728 low-dropout, pulse-width-modulated (PWM) DC-DC buck regulator is optimized to provide power to the PA in 2.5G/3G cellular phones; however, they may be applied in many other applications where high efficiency is a priority. The supply voltage range is from 2V to 5V, and the guaranteed output current is 1.5A. 1.2MHz PWM switching allows for small external components, while skip mode reduces quiescent current to 220µA with light loads. ! ! ! ! ! ! Patent Number #6,452,366 1.2MHz switching and synchronization Fast output setting slew rate < 30µs Dynamic output-voltage adjustment from 0.8V to 4V Source and sink up to 1.
