The TPS5683x is a high-efficiency, easy-to-use, synchronous buck converter with a wide input voltage range of 4.5V to 28V. The device supports up to 8A continuous output current at output voltages between 0.6V and 13V.

The TPS5683x uses D-CAP3 control mode to provide fast transient response, good line and load regulation, no requirement for external compensation, and supports low equivalent series resistance (ESR) output capacitors like MLCC.

The TPS56837 operates at Eco-mode to attain high efficiency at light load. The TPS56838 operates in forced continuous conduction mode which maintains lower output ripple during all load conditions. The TPS56836 operates in Out-of-Audio mode to avoid audible noise.

The TPS5683x has three selectable switching frequencies, 500kHz, 800kHz, and 1200kHz, and selectable current limit through MODE pin configuration. The TPS5683x has adjustable soft-start time by connecting the SS capacitor and with default 1.8ms with the SS pin floating.

The TPS5683x provides complete non-latched OV (overvoltage), UV (undervoltage), OC (overcurrent), OT (overtemperature) and UVLO (undervoltage lockout) protections combined with power-good indicator and output discharge function features.

The TPS5683x is available in a 10-pin, 3.0mm × 3.0mm, HotRod QFN package, and the junction temperature is specified from –40°C to 150°C.
