DESCRIPTION  
The TPS55383 and TPS55386 are dual output,  
non-synchronous buck converters capable of  
supporting 3-A output applications that operate from a  
4.5-V to 28-V input supply voltage, and require output  
voltages between 0.8 V and 90% of the input voltage.

2.1-ms Internal Soft Start  
Dual PWM Outputs 180° Out-of-Phase  
Ratiometric or Sequential Startup Modes  
Configurable as Dual Output or Two-Channel  
Single Output Multiphase for 6 amp Capability  
With an internally-determined operating frequency  
and soft start time, these converters provide many  
features with a minimum of external components. The  
outputs of the two error amplifiers are accessible  
allowing user optimization of the feedback loop under

Pulse-by-Pulse Overcurrent Protection  
Thermal Shutdown Protection at +148°C  
16-Pin PowerPAD™ HTSSOP package  
Channel 1 overcurrent protection is set at 4.5 A, while  
Channel 2 overcurrent protection level is selected by  
connecting a pin to ground, to BP, or left floating. The  
setting levels are used to allow for scaling of external  
components for applications that do not need the full  
load capability of both outputs.  
APPLICATIONS  
•
•
•
•
Set Top Box  
Digital TV  
Power for DSP  
Consumer Electronics  
The outputs may be enabled independently, or  
configured to allow either ratiometric or sequential  
startup sequencing. Additionally, the two outputs may  
be powered from different sources.
