30 / 101 page ZSPM15xx Datasheet © 2016 Integrated Device Technology, Inc. 30 January 27, 2016 3.3.3. Digital Compensator The sampled output voltage is processed by a digital control loop in order to modulate the DPWM output signals controlling the power stage. This digital control loop works as a voltage-mode controller using a PID-type compensation. The basic structure of the controller is shown in Figure 3.1. The proprietary State-Law™ Control (SLC) concept features two parallel compensators for steady-state operation and fast transient operation. This allows tuning the compensators individually for the respective needs; i.e., quiet steady state and fast transient performance. The ZSPM15xx implements fast, reliable switching between the different compensation modes in order to ensure good transient performance and a quiet steady state. Figure 3.1 Simplified Block Diagram of the Digital Compensation Two techniques are used to improve transient performance further: • Tru-sample Technology™ is used to acquire fast, accurate, and continuous information about the output vol- tage so that the device can react quickly to any change in output voltage. Tru-sample Technology™ reduces phase-lag caused by sampling delays, reduces noise sensitivity, and improves transient performance. • A nonlinear gain adjustment is used during large load transients to boost the loop gain and reduce the settling time. The control loops in the ZSPM15xx are preconfigured and can be selected using a pin-strapping option. A range of different output capacitors is supported.
