The proprietary D-CAP2™ mode control supports low ESR output capacitors such as specialty polymer capacitors and multi-layer ceramic capacitors without complex external compensation circuits. The fast transient response of D-CAP2™ mode control can reduce the output capacitance required to meet a specific level of performance. 8.2 Functional Block Diagram Figure 17. TPS562210 8.3 Feature Description 8.3.1 The Adaptive On-Time Control and PWM Operation The main control loop of the TPS562210 and TPS563210 are adaptive on-time pulse width modulation (PWM) controller that supports a proprietary D-CAP2™ mode control. The D-CAP2™ mode control combines adaptive on-time control with an internal compensation circuit for pseudo-fixed frequency and low external component count configuration with both low ESR and ceramic output capacitors. It is stable even with virtually no ripple at the output. Copyright © 2015, Texas Instruments Incorporated Submit Documentation Feedback 11 Product Folder Links: TPS562210 TPS563210 |
