The NSI50350A is designed to provide a thermally efficient and cost-effective alternative to passive/discrete components or driver integrated circuit solutions for current regulation of LEDs.

ON Semiconductor (Phoenix, AZ) (Nasdaq: ONNN) has expanded its portfolio of Constant Current Regulators (CCRs) to include the NSI50350A. This simple and extremely robust device is designed to provide a thermally efficient and cost-effective alternative to passive/discrete components or driver integrated circuit (IC) solutions for current regulation of Light Emitting Diodes (LEDs). The device is ideal for a variety of 1 watt (W) lighting applications including automotive, architectural lighting, and signage. Features include:

• Self-Biased Transistor (SBT) technology.
• A built-in LED driver.
• A negative temperature coefficient to protect LEDs from thermal runaway at extreme voltages and currents.
• A milliamp (mA) ± 10% steady state regulation current (Ireg).
• An operating temperature range of −55° to +175 °C.
• A high anode-cathode voltage (Vak) rating of 50 volts (V) maximum, which enables the device to withstand voltage surges that are common in automotive, industrial, and commercial signage applications.
• Offered in both DPAK-4 (NSI50350AD) or SMC (NSI50350AS) industry standard packages, and are capable of dissipating 11 W and 5.8 W respectively.
