AnDAPT Inc AMP8D6_RevH | Demoboard MULTIPHASE

Description

The C510 Power Component is a customizable PWM Multiphase Synchronous Buck, Current Mode Switching Regulator. Combine the C510 component with other Power Components to create a custom-defined, AnDAPT AmP on-demand power management device. The integrated, low-resistance switching Scalable Integrated MOSFETs (SIMs) provide up to 6A output current. The maximum current for the C510 Power Component is defined by the number of phases (2, 3, or 4) and the maximum current of the selected AmP device. Output voltage feedback is compared against an internal reference using a high-performance, voltage-error amplifier that provides tight voltage regulation accuracy under transient conditions. Pulse-width modulated (PWM), current-mode regulation is implemented with PID and slope compensation. The switching frequency is either generated internally via an oscillator with selectable frequencies or provided via an external pin. The C510 component has a customizable current switchover point between pulse-width modulation (PWM) for higher-current loads and pulse-skipping modulation (PSM) for low-current loads. The customizable output voltage is specified by the power engineer during customization using AnDAPT’s cloudbased WebAmp development software. The C510 component has customizable control and status pins including an optional enable input, an optional power-good output, and optional output flags to signal when the system triggers an overvoltage (OVP), overcurrent (OCP), or undervoltage lockout (UVLO) condition. The threshold values are specified by the power engineer using the WebAmp tool. The customizable soft-start and soft-stop slew rates plus ramp timing are also specified by the power engineer using the WebAmp tool.
