Part # Name Product Family Comments
TPS40100   Wide Input Range Synchronous Buck Controller for Sequencing   CONTROLLER (EXTERNAL SWITCH) - STEP-DOWN (BUCK) CONTROLLER    The TPS40195 is a flexible, feature rich synchronous buck controller that operates from a nominal 4.5 V to 20 V supply. This controller implements voltage mode control with the switching frequency adjustable from 100 kHz to 600 kHz.  
TPS40140   Stackable 2 Channel Multiphase or 2 Channel Independent Output Controller   DC/DC SWITCHING REGULATOR - DC/DC Multi-phase    The TPS40140 is a multi-functional synchronous buck controller that can be configured to provide either a single-output two-phase power supply or a power supply that supports two independent outputs. Several TPS40140 controllers can be stacked up to a 16-phase multi-phase single output power supply. Alternatively, several controllers providing multiple independent outputs can be synchronized in an interleaving pattern for improved input ripple current.  
TPS40180   Single Phase Stackable Controller   DC/DC SWITCHING REGULATOR - DC/DC Multi-phase    The TPS40180 is a stackable single-phase synchronous buck controller. Stacking allows a modular power supply design where multiple modules can be connected in parallel to achieve the desired output power capability if the output power requirement cannot be provided by one module.  
TPS40192   4.5V to 18V Input, Low Pin Count, Synchronous Buck Controller with Power Good   CONTROLLER (EXTERNAL SWITCH) - STEP-DOWN (BUCK) CONTROLLER    TPS40192 is a cost-optimized synchronous buck controller that operate from 4.5 V to 18 V input. These controllers implement a voltage-mode control architecture with the switching frequency fixed at 600 kHz . The higher switching frequency facilitates the use of smaller inductor and output capacitors, thereby providing a compact power-supply solution. An adaptive anti-cross conduction scheme is used to prevent shoot through current in the power FETs.  
TPS40193   4.5V to 18V Input, Low Pin Count Synchronous Buck Controller with Power Good   CONTROLLER (EXTERNAL SWITCH) - STEP-DOWN (BUCK) CONTROLLER    TPS40193 is a cost-optimized synchronous buck controller that operate from 4.5 V to 18 V input. These controllers implement a voltage-mode control architecture with the switching frequency fixed at 300 kHz . An adaptive anti-cross conduction scheme is used to prevent shoot through current in the power FETs.  
TPS40195   4.5V to 20V Buck Controller with Synchronization and Power Good   CONTROLLER (EXTERNAL SWITCH) - STEP-DOWN (BUCK) CONTROLLER    The TPS40195 is a flexible, feature rich synchronous buck controller that operates from a nominal 4.5 V to 20 V supply. This controller implements voltage mode control with the switching frequency adjustable from 100 kHz to 600 kHz.  
TPS40322   Dual Output or Two-phase Synchronous Buck Controller   DC/DC SWITCHING REGULATOR - DC/DC Multi-phase    The TPS40322 is a dual-output, synchronous buck controller. It can also be configured as a single-output, two-phase controller. The 180� out-of-phase operation reduces the input current ripple and extends the input capacitor lifetime.
