产品详细介绍
"DC/DC -> 升压IC
The XZ1301 is a compact, high efficiency, and low
voltage step-up DC/DC converter with an Adaptive
Current Mode PWM control loop. It comprises of an
error amplifier, a ramp generator, a PWM comparator, a
switch pass element and the driver. It provides stable
and high efficient operation over a wide range of load
currents without external compensation. The below 1V
start-up input voltage makes XZ1301 suitable for single
battery cell applications. The built-in power transistor is
able to provide up to 300mA output current while
working under Li-Battery Supply. Besides, it provides
extra pin to drive external power devices (NMOS or
NPN ) in case higher output current is needed. The
output voltage is set with two external resistors. The
500KHz high switching rate reduces the size of external
components. Besides, the 14μA low current
together with high efficiency maintains long battery
lifetime.
