LNK305PN 제품 상세 정보
Description
LinkSwitch-TN is specifically designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360 mA output current range at equal system cost while offering much higher performance and energy efficiency. LinkSwitch-TN devices integrate a 700 V power MOSFET, oscillator, simple On/Off control scheme, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit Figure 1. Typical Buck Converter Application (See Application Examples Section for Other Circuit Configurations). and thermal shutdown circuitry onto a monolithic IC. The start-up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias supply and associated circuitry in buck or flyback converters. The fully integrated auto-restart circuit in the LNK304-306 safely limits output power during fault conditions such as short-circuit or open loop, reducing component count and system-level load protection cost. A local supply provided by the IC allows use of a nonsafety graded optocoupler acting as a level shifter to further enhance line and load regulation performance in buck and buck-boost converters, if required.
Product Highlights

ON/OFF: On/Off control pin. Connect to a control circuit to enable or disable the IC.
GND: Ground pin. Connect to the ground reference of the circuit.
D: Drain pin. Connect to the power MOSFET's drain terminal.
S: Sense pin. Connects to the output voltage to sense the voltage level.
VCC: Voltage control pin. Connect to an external capacitor for setting the startup voltage.
BP/M: Brownout protection/Multiplex pin. Used for multiple functions based on application requirements.
NC: No connection. This pin is not internally connected and should be left unconnected.
NC: No connection. This pin is not internally connected and should be left unconnected.
