Description
Electronic Component Model: NCP1212PG
Product Category: AC DC Converters, Offline Switchers
Specifications and features
NCP1212 is a high-performance current mode PWM controller specifically designed for off−line and DC−to−DC converter applications. The device requires very few external components and offers designer additional protection for better system reliability. The device features a trimmed oscillator for precise Duty Cycle control, accurate bandgap voltage reference, high gain error amplifier, current sensing comparator, and a high current totem pole output gate driver that ideally drives the external power MOSFET. The device operates in current mode up to 200 kHz and has inherent feed-forward compensation. It also has latching PWM for cycle−by−cycle current limiting and a low startup and operating current. The NCP1212 has internal undervoltage lockout with hysteresis, internal leading-edge blanking for current feedback, and a direct interface with Optocoupler for secondary sensing. It also has a built−in soft−start function that is programmable by an external capacitor. The maximum duty cycle is user programmable with options for 48% or 82%. The NCP1212 provides output overvoltage protection against open loop and AC line brownout detect protection. It also has output overload protection irrespective of the auxiliary voltage level.
Application Scenarios
The NCP1212 is suitable for various applications including ATX PC power supplies, universal input wall mount adaptors, CRT monitors, and all flyback and forward SMPS systems.
