Transient Enhancement
The NCP1589L is a low cost PWM controller designed to operate
from a 5 V or 12 V supply. This device is capable of producing an
output voltage as low as 0.8 V and converting voltage from as low as
2.5 V . It is easy to operate and provides an optimal level of integration
to reduce size and cost of the power supply. It operates in Ramp Pulse
Modulation mode for superior load step and release response. In
addition to fast transient response, it also includes a 1.5 A gate driver
design and light load efficiency features such as adaptive nonïoverlap
circuitry and diode emulation. It normally operates at a range of
200ï500 kHz in continuous current conduction mode, which reduces
with current at light load for further power saving. Protection features
include programmable overcurrent protection, output overvoltage and
undervoltage protection and input undervoltage lockout (UVLO).
