NCP1030, NCP1031
Low Power PWM Controller
with On鈭扖hip Power Switch
and Startup Circuits for
48 V Telecom Systems
The NCP1030 and NCP1031 are a family of miniature high鈭抳oltage
monolithic switching regulators with on鈭抍hip Power Switch and Startup
Circuits. The NCP103x family incorporates in a single IC all the active
power, control logic and protection circuitry required to implement, with
minimal external components, several switching regulator applications,
such as a secondary side bias supply or a low power dc鈭抎c converter.
This controller family is ideally suited for 48 V telecom, 42 V automotive
and 12 V input applications. The NCP103x can be configured in any
single鈭抏nded topology such as forward or flyback. The NCP1030 is
targeted for applications requiring up to 3 W, and the NCP1031 is
targeted for applications requiring up to 6 W.
The internal error amplifier allows the NCP103x family to be easily
configured for secondary or primary side regulation operation in
isolated and non鈭抜solated configurations. The fixed frequency oscillator
is optimized for operation up to 1 MHz and is capable of external
frequency synchronization, providing additional design flexibility. In
addition, the NCP103x incorporates individual line undervoltage and
overvoltage detectors, cycle by cycle current limit and thermal
shutdown to protect the controller under fault conditions. The preset
current limit thresholds eliminate the need for external sensing
components.
