Ordering Information
Description
low voltage step-up DC/DC converter with an
Adaptive Current Mode PWM control loop,
includes an error amplifier, ramp generator,
comparator, switch pass element and driver in
which providing a stable and high efficient
operation over a wide range of load currents. It
operates in stable w***eforms without external
compensation.
The low start-up input voltage below 1V makes
applicati*** of providing up to 300mA output
current. The 800KHz high switching rate
minimized the size of external components.
Besides, the 30
μ
A low quiescent current
together with high efficiency maintains
