DPA425R, DC/DC Flyback, Forward Regulator, Adjustable, 16V to 75V In, 400kHz, TO-263-7C-6

Полупроводники - Микросхемы\Микросхемы Управления Питанием\Стабилизаторы Напряжения\Регулируемые Импульсные DC - DC Стабилизаторы DPA-Switch™ IC family is a highly integrated solution for DC-DC conversion applications with 16-75VDC input. DPA-Switch uses the same proven topology as TOPSwitch™, cost effectively integrating a power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip. High performance features are enabled with three user configurable pins. In addition, all critical parameters (i.e. current limit, frequency, PWM gain) have tight temperature and absolute tolerance, to simplify design and reduce system cost. It eliminates up to 50 external components-saves space and cost. The device integrates 220V high frequency MOSFET, PWM control. It features extremely low consumption at no-load and cycle skipping at light load for high standby efficiency. Applications includes PoE applications, VoIP phones, WLAN, security cameras, telco central office equipment: xDSL, ISDN, PABX, distributed power architectures (24V/48V bus) and industrial controls. • Maximum power output of 70W (forward), 52W (flyback) at 36-75VDC input range • Highly integrated DC-DC converter ICs for power over Ethernet and telecom applications • Superior performance and flexibility EcoSmart™ energy efficient • Built-in auto-restart for output overload/open loop protection • Pin selectable 300/400KHz fixed frequency, wide input (line) voltage range: 16-75VDC • Externally programmable current limit, source connected tab reduces EMI • Line undervoltage (UV) detection: meets ETSI standards, line overvoltage (OV) shutdown protection • UV/OV limits gate drive voltage for synchronous rectification, supports forward or flyback topology • Fully integrated soft-start for minimum stress/overshoot • Cycle skipping: regulation to zero load without pre-load, hysteretic thermal shutdown
