PRODUCTION DATA
The TPSM8A28 and TPSM8A29 power modules feature high effcieincy and small footprint. These devices are suitable for low voltage point-of-load applications up to 15 A. The conversion input voltage ranges from 2.7 V to 16 V, and the external VCC input voltage ranges from 4.75 V to 5.3 V, and output voltage ranges from 0.6 V to 5.5 V. These power modules uses D-CAP3™ mode control combined with adaptive on-time architecture. The D-CAP3™ mode uses emulated current information to control the modulation and tracks the preset switching frequency over a wide range of input and output voltages. Advantages of this control scheme is that it does not require a phase-compensation network outside, which makes the device easy-to-use and also allows low external component count. Further 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). It also adjusts switching frequency as needed during load-step transient.
