The TPSM8663x 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. TPSM8663x supports up to 6A continuous output current, which output voltage is between 0.6V and 13V.
The TPSM8663x 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 TPSM86638 operates in forced continuous conduction mode (FCCM) during light load which maintains lower output ripple during all load conditions. TPSM86637 operates at Eco-mode to attain high efficiency at light load.
The TPSM8663x 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 TPSM8663x 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.
