产品详细介绍
description：
the me2129 series is a cmos
step-up switching regulator which mainly consists of a
reference voltage source, an oscillation circuit,an error
amplifier, a phase compensation circuit,a pwm/pfm switching control
circuit. with an external low-on-resistance nch power mos,this
product is applicable to applications re high efficiency and
high output current.
the me2129 series switches its operation to the pfm control circuit
whose duty ratio is 15 % with to the pwm/pfm switching control
circuit under a light load and to prevent decline in the efficiency
by ic operation current.
typical application:
mobile phones
(pdc, gsm, cdma, imt200 etc.)
bluetooth e
pda
portable communication modem
portable games
cameras
digital cameras
cordless phones
notebook computers
feature：
low voltage operation:
start-up is guaranteed from 0.9 v(iout =1 ma )
duty ratio: built-in pwm/pfm switching control circuit 15 to
78 % .
