TNY277PN

The TNY277PN is an integrated Power MOSFET and PWM controller designed for compact, reliable power conversion in both consumer and industrial applications. Combining a high-voltage MOSFET with an on-chip controller, the device delivers efficient switching and stable operation while minimizing external component count and simplifying circuit design. 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 designs. The integrated architecture of the TNY277PN reduces the need for numerous external parts, which simplifies PCB layout and lowers overall system cost. High-frequency operation enables smaller magnetics and passive components, improving power density while maintaining thermal performance. Built-in protection mechanisms guard against overload and thermal stress, contributing to safe, durable operation under varying load conditions. Ideal for switch-mode power supplies and other power conversion roles where reliable high-voltage performance and low standby consumption are priorities, the TNY277PN offers a practical balance of features that support efficient, compact, and maintainable designs.
