Description

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.
