TPSM82810SSILR – TEXAS INSTRUMENTS

The TPSM82810SSILR is a 10-channel, 2A synchronous step-down converter from Texas Instruments, packaged in a 40-pin, 7x7mm QFN package. It features independent output voltage regulation for each of its ten channels, each capable of delivering up to 2A of continuous current. Each channel utilizes a constant-frequency, current-mode control architecture, enabling fast transient response and excellent load regulation. Input voltage ranges from 4.5V to 18V, allowing for flexibility in system design. Output voltage per channel is adjustable from 0.8V to 5.5V via external resistors, providing precise voltage scaling for diverse loads._x000D_

Key features include integrated high-side and low-side MOSFETs, minimizing external component count and solution size. The device incorporates overcurrent protection, overtemperature shutdown, and short-circuit protection for robust operation. Its high efficiency, typically exceeding 90% across the operating range, minimizes power dissipation and improves thermal performance. Common applications include powering multiple independent loads in complex systems like industrial automation, instrumentation, and telecom equipment where precise and isolated voltage rails are crucial. The TPSM82810SSILR’s multi-channel capability simplifies design by eliminating the need for multiple single-channel converters, reducing board space and simplifying power distribution.
