The TPSM8F7x20 is a power-dense, quad-channel buck power module designed to provide efficient and reliable power conversion for a wide output voltage range from 0.6V to 11V. The module integrates MOSFETs, inductor, and select capacitors to reduce board space and layout complexity. The module can be configured into both multiphase and multioutput rails by supporting 2, 3, and 4-phase stackability with interleaved phases. Under steady state conditions, the module operates in FCCM with a fixed-frequency that is resistor adjustable from 400kHz to 2.2MHz and synchronizable to an external clock. The TPSM8F7x20 module employs current mode control with internal and external compensation. Sequencing requirements are easily met with the external soft start, active output discharge, adjustable EN, and power-good features. A full suite of protection features (overvoltage protection (OVP), undervoltage protection (UVP), input undervoltage lockout (UVLO), overtemperature (OT), overcurrent (OC)) are also included for robustness.
