产品详细介绍
description:
the me2109 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 me2109 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.
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 %
.
oscillator frequency:300khz
external parts: coil, diode, capacitor, and transistor
output voltage range: 1.5v ~6.5 v
output voltage accuracy:±2%
soft start function: 2 ms.
package:sot-23-5
