31 / 68 page  UCD3138 www.ti.com SLUSAP2 A – MARCH 2012 – REVISED MARCH 2012 4.5 DPWM Modes of Operation The DPWM is a complex logic system which is highly configurable to support several different power supply topologies. The discussion below will focus primarily on waveforms, timing and register settings, rather than on logic design. The DPWM is centered on a period counter, which counts up from 0 to PRD, and then is reset and starts over again. The DPWM logic causes transitions in many digital signals when the period counter hits the target value for that signal. 4.5.1 Normal Mode In Normal mode, the Filter output determines the pulse width on DPWM A. DPWM B fits into the rest of the switching period, with a dead time separating it from the DPWM A on-time. It is useful for buck topologies, among others. Here is a drawing of the Normal Mode waveforms: Copyright © 2012, Texas Instruments Incorporated Functional Overview 31 Submit Documentation Feedback Product Folder Link(s): UCD3138 |
