The DIY8883 integrates internal high-side and low-side power MOSFETs for high efficiency without an external Schottky diode and is available in a 16-pin QFN3x3 package. With internal compensation and feedback divider, the DIY8883 can offer a very compact solution with a minimum number of readily available standard external components.
The DIY8883 is designed to be very versatile. The output voltage level can be adjusted from 0.6V to 12V, on the fly through an I2C serial interface. Voltage slew rate, switching frequency, enable and power savings mode are also programmable via the I2C interface. This allows users to optimize each output for their particular requirements.
During bench evaluations, different configurations can be easily obtained through the I2C interface instead of reworking external components. Once the desired optimum setting has been reached, a multipage one-time programmable memory is available allowing the settings to be permanently stored.
Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include under-voltage lockout (UVLO), over-voltage protection (OVP), over-current protection (OCP) and over-temperature protection (OTP).
