The APW7077/A series are multi- function PWM
step-up DC-DC converter with an adaptive voltage mode
controller and higher efficiency application from one to
four cells battery packs. The APW7077/A series are
set PWM operating mode, voltage-mode to follow
portable application. And built-in driver pin, EXT pin,
for connecting to an external transistor or MOSFET
during light load, the device will automatically skip
switching cycles to maintain high efficiency. The
APW7077/A series consists of PWM controller,
reference voltage, phase compensation, oscillator,
soft-start, driver block. It will provide to operate suitable
voltage without external compensation circuit. The
APW7077/A series have fixed voltage and adjustable
voltage version from a wide input voltage ranges 0.7V
to 5.5V for step-up DC-DC converter. The start-up is
guaranteed at 1V and the device is operating down to
0.7V. And providing up to 300mA loading current.
Besides, low quiescent current (switch-off) is
guaranteed.
Low Start-up Voltage 0.9V
Fixed 300kHZ Operating Frequency
Built-In Internal Soft Start Circuit
Low Operating Current
3.3V and 5V (
±
2.5%) Fixed (APW7077) or
Adjustable Output Voltage (APW7077A)
High Efficiency Up to 88% at 400mA
Output Current
High Output Current Up to 1A
