The TPSM8683x is a high-efficiency, high-voltage input, easy-to-use, synchronous buck power module. The device integrates power MOSFETs, a shielded inductor, and basic passives, minimizing the design size.
With the wide operating input voltage range of 4.5V to 28V, this device is an excellent choice for systems powered from 12V, 19V, 24V power-bus rails. TPSM8683x supports up to 8A continuous output current, which output voltage is between 0.6V and 5.5V.
The TPSM8683x uses DCAP3 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 TPSM86838 operates in forced continuous conduction mode (FCCM) during light load which maintains lower output ripple during all load conditions. TPSM86837 operates at Eco-mode to attain high efficiency at light load.
The TPSM8683x provides complete non-latched OV (Undervoltage), UV (Undervoltage), OC (Overcurrent), OT (Overtemperature), and UVLO (Undervoltage lockout) protections combined with power-good indicator and output discharge function features.
The TPSM8683x is available in a 19-pin 5.0mm × 5.5mm HotRod QFN package, and the junction temperature is specified from –40°C to 150°C.
