TPS553864.5V to 28V Input, Dual 3A Outputs, 600kHz Step-Down Converter with External Compensation | Power Management (PMIC) | 2 | Active | 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.
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 a wide range of output filter characteristics. 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.
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.

TPS561005 Bit Programmable Synchronous Buck Controller | Power Management (PMIC) | 1 | Obsolete | The TPS56100 is a high-efficiency synchronous-buck regulator controller which provides an accurate programmable supply voltage to low-voltage digital signal processors, such as the `C6x and `C54x DSPs. An internal 5-bit DAC is used to program the reference voltage from 1.3 V to 2.6 V. Higher output voltages can be implemented using an external input resistive divider. The TPS56100 uses a fast hysteretic control method that provides a quick transient response. The propagation delay from the comparator input to the output driver is less than 300 ns, even at maximum output current. Overcurrent shutdown and crossover protection combine to eliminate destructive faults in the output MOSFETs, thereby protecting the processor during operation. The slowstart current source is proportional to the reference voltage, thereby eliminating variation of the slowstart timing when changes are made to the output voltage. When the output drops to less than 93% of the nominal output voltage, PWRGD will pull the open-drain output low. The overvoltage circuit will disable the output drivers if the output voltage rises more than 15% above the nominal output voltage. The TPS56100 also includes an inhibit input to control power sequencing and undervoltage lockout thereby insuring the 5-V supply is within limits before the controller starts. The 2-A MOSFET drivers can power multiple MOSFETs in parallel to drive single or multiple DSPs and load currents up to 30 A. The high-side driver can be configured as a ground-referenced driver or as a floating bootstrap driver with the included internal bootstrap Schottky diode.
The TPS56100 is available in a 28-pin TSSOP PowerPAD package, which increases thermal efficiency and eliminates bulky heat sinks.
