Description for the TPS92640

The TPS92640 and TPS92641 devices are high-voltage, synchronous NFET controllers for buck-current regulators. Output current regulation is based on valley current-mode operation using a controlled on-time architecture. This control method eases the design of loop compensation while maintaining nearly constant switching frequency. The TPS92640 and TPS92641 devices include a high-voltage start-up regulator that operates over a wide input range of 7 V to 85 V. The PWM controller is designed for high speed capability, including an oscillator frequency range up to 1 MHz. The deadtime between high side and low side gate driver is optimized to provide very high efficiency over a wide input operating voltage and output power range. The TPS92640 and TPS92641 devices accept both analog and PWM input signals, resulting in exceptional dimming control range. Linear response characteristics between input command and LED current is achieved with true zero LED current using low off-set error amplifier and proprietary PWM dimming logic. Both devices also include precision reference capable of supplying current to low power microcontroller. Protection features include cycle-by-cycle current protection, overvoltage protection, and thermal shutdown. The TPS92641 device includes a shunt FET dimming input and MOSFET driver for high resolution PWM dimming.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
