TNY278PN

The TNY278PN is an integrated Power MOSFET and PWM controller designed for compact, reliable power conversion in both consumer and industrial applications. By pairing a high-voltage MOSFET with an on-chip PWM controller, the device delivers efficient switching and stable regulation while minimizing external component count and simplifying circuit topology for streamlined designs. 700 V breakdown voltage for robust handling of high-voltage inputs. 0.4 A maximum current to support moderate power range applications. Built-in 132 kHz oscillator frequency that provides precise timing for efficient switching. Low standby power consumption to reduce energy waste during idle periods. Compact DIP-7 package for easy integration into space-constrained layouts. The integrated architecture of the TNY278PN reduces the number of required external parts, simplifying PCB layout, reducing assembly complexity, and lowering system cost. High-frequency operation enables the use of smaller magnetics and reduced passive component values, improving power density and allowing smaller overall power supply footprints. Thermal considerations are simplified by the single-package solution, and the device's internal control circuitry supports predictable dynamic behavior across a range of loads. Built-in protection mechanisms provide safeguards against overload and thermal stress, helping to ensure safe and durable operation under varying line and load conditions. Typical applications include switch-mode power supplies, standby and adapter power stages, and other isolated or non-isolated power conversion roles where reliable high-voltage performance, low quiescent consumption, and compact form factor are priorities.
