Three Selectable Levels of Overcurrent
Protection (Output 2)
The TPS54383 and TPS54386 are dual output,
non-synchronous
buck
converters
capable
of
0.8-V 1.5% Voltage Reference
supporting 3-A output applications that operate from a
2.1-ms Internal Soft Start
4.5-V to 28-V input supply voltage, and require output
Dual PWM Outputs 180° Out-of-Phase
voltages between 0.8 V and 90% of the input voltage.
Ratiometric or Sequential Startup Modes
With an internally-determined operating frequency,
Selectable by a Single Pin
soft start time, and control loop compensation, these
85-m Internal High-Side MOSFETs
converters provide many features with a minimum of
external
components.
Channel

overcurrent
Current Mode Control
protection is set at 4.5 A, while Channel 2 overcurrent
Internal Compensation (See Page 16)
protection level is selected by connecting a pin to
Pulse-by-Pulse Overcurrent Protection
ground, to BP, or left floating. The setting levels are
used to allow for scaling of external components for
Thermal Shutdown Protection at +148°C
applications that do not need the full load capability of
14-Pin PowerPAD HTSSOP package
both outputs.
The outputs may be enabled independently, or may
be configured to allow either ratiometric or sequential

be powered from different sources.
