PRODUCTION DATA
The device can be used in peak current mode (PCM) control or voltage mode (VM) control. When the converter is operating in PCM, the voltage amplifier output will regulate the converter's peak current and duty cycle. When the device is used in VM control, the voltage amplifier output will regulate the power converter's duty cycle. The regulation of the system's peak current and duty cycle can be achieved with the use of the integrated error amplifier and external feedback circuitry.
