升压DC-DC 转换IC SOT23-5封装 ME2129C535M5G 优质供应
税前: ¥0.68
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
requiring 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.
Feature:
lLow voltage operation: Start-up is guaranteed from
0.9 V(IOUT =1 mA )
lDuty
ratio:
Built-in
PWM/PFM
switching
control
circuit 15 to 78 % .
loscillator frequency:300KHz
lExternal parts: coil, diode, capacitor, and transistor
lOutput voltage range: 1.5V ~6.5 V
lOutput voltage accuracy:±2%
lSoft start function: 2 ms.
lPACKAGE:SOT-23-5
