General Description
The APW7075 is a PWM/PFM, high-efficiency and
step-up DC-DC converter with an integrated LDO input
switch for dual mode application. During battery mode
operation, the APW7075 acts as synchronous recti-
fier and step-up DC-DC converter with a fixed or ad-
justable output voltage. When the VIN pin sense 5V
input voltage, the APW7075 is switched to LDO op-
eration mode, maintaining the constant output voltage.
The input voltage ranges from 0.6 V to 4.5V for step-
up DC-DC converter. The start-up is guaranteed at1V
and the device is operating down to 0.6V. When the
device is at LDO operating mode, the suitable output
voltage 3.3V and loading current 500mA for maximum
power consumption are guaranteed.
The APW7075 is suited for dual mode and portable
battery powered appliance with low-battery detector.
In dual-mode applications, the APW7075 draws power
from any available 5V USB connection and reverts to
battery power when the USB power is removed.
