The TNY277PN IC family features a design flexible solution with a low system cost and extended power capability. It offers simple ON/OFF control without the need for loop compensation. The selectable current limit via BP/M capacitor value allows for customization based on application requirements.
The higher current limit extends peak power or improves efficiency in enclosed adapters/chargers. Additionally, the tight I2f parameter tolerance reduces system cost while maximizing power delivery efficiency. The IC also features pin-out simplification for heat sinking to the PCB.
Frequency jittering capability reduces EMI filter costs, making it a cost-effective choice for various applications. The TNY277PN is self-biased, eliminating the need for bias winding or components. Its ON-time extension feature extends low line regulation range and hold-up time, reducing the required input bulk capacitance.
The TNY277PN IC's SOURCE pins are electrically quiet, contributing to low EMI. This IC is a versatile solution for power management needs, offering reliability and efficiency in a compact package.
