The TPSM8A28 and TPSM8A29 power modules feature an integrated power inductor and some basic passives. The devices are small and highly efficient, suitable for low output voltage point-of-load applications up to 15 A. These devices features proprietary D-CAP3™ mode control combined with adaptive on-time architecture. This combination builds modern low-duty-ratio and ultra-fast load-step-response DC/DC converters in an ideal fashion. The output voltage ranges from 0.6 V to 5.5 V. The conversion input voltage ranges from 2.7 V to 16 V, and the VCC input voltage ranges from 4.75 V to 5.3 V. The D-CAP3™ control mode uses emulated current information to control the modulation. An advantage of this control scheme is that it does not require an external phase-compensation network, which makes the device easy to use and also allows for a low external component count. Another advantage of this control scheme is that it supports stable operation with all low-ESR output capacitors (such as ceramic capacitor and low-ESR polymer capacitor). Adaptive on-time control tracks the preset switching frequency over a wide range of input and output voltages while increasing switching frequency as needed during a load-step transient.
