3 Description
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.
