Product Information
Product Overview
The NCP1200P100G is a current-mode Pulse Width Modulation (PWM) Controller for low-power universal off-line supplies. It represents a major leap toward ultra-compact switchmode power supplies. Due to a novel concept, the circuit allows the implementation of a complete offline battery charger or a standby SMPS with few external components. With an internal structure operating at a fixed 100kHz, the controller drives low gate-charge switching devices like an IGBT or a MOSFET thus requiring a very small operating power. Due to current-mode control, the NCP1200 drastically simplifies the design of reliable and cheap offline converters with extremely low acoustic generation and inherent pulse-by-pulse control.
