The TLVM1440x is a highly integrated, 36V input capable, DC/DC design that combines power MOSFETs, a shielded inductor, and passives in an enhanced HotRod™ QFN package. The device supports either dual output or high current single output using an interleaved, stackable, current-mode control architecture for easy loop compensation, fast transient response, excellent load and line regulation. The module has VIN and VOUT pins located at the corners of the package for optimized input and output capacitor placement. A large thermal pad beneath the module enable a simple layout and easy handling in manufacturing. With an output voltage from 1V to 9V, the TLVM1440x is designed to quickly and easily implement a low-EMI design in a small PCB footprint. The total design requires as few as six external components and eliminates the magnetics selection from the design process. Although designed for small size and simplicity in space-constrained applications, the TLVM1440x module offers many features for robust performance: precision enable with hysteresis for adjustable input-voltage UVLO, along with integrated VCC, bootstrap and input capacitors for increased reliability and higher density. The module is configured for automatically switching between constant switching frequency (FPWM) at higher loads to variable frequency (PFM) for higher light load efficiency. Including a PGOOD indicator for sequencing, fault protection, and output voltage monitoring.
