3 Description
The TPS56837 is a high-efficiency, easy-to-use,
synchronous buck converter with a wide input voltage
range of 4.5 V to 28 V, and supports up to 8-A
continuous output current at output voltages between
0.6 V and 13 V.
The TPS56837 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 with three selectable
switching frequencies: 550 kHz, 880 kHz, and 1300
kHz and selectable current limit through MODE pin
configuration. The TPS56837 has adjustable soft-start
time with default 1.8 ms by SS pin.
The TPS56837 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 TPS56837 is available in a 10-pin 3.0-mm ×
3.0-mm HotRod QFN package, and the junction
temperature is specified from –40°C to 150°C.
