NCP1561
Push鈭扨ull PWM Controller
for 48 V Telecom Systems
The NCP1561 Push鈭扨ull PWM controller contains all the features
and flexibility needed to implement high efficiency dc鈭抎c converters
using voltage or current鈭抦ode control. This device can be configured
in any dual ended topology such as push鈭抪ull or half鈭抌ridge. It can
also be used for forward topologies requiring a 50% maximum duty
cycle. This device is ideally suited for 48 V telecom, 42 V automotive
systems and 12 V input applications.
The NCP1561 cost effectively reduce system part count by
incorporating a high voltage startup regulator, line undervoltage
detector, single resistor oscillator setting, dual mode overcurrent
protection, soft鈭抯tart and single resistor feedforward ramp generator.
The oscillator frequency can be adjusted up to 250 kHz.
