It enables designers to solve high-current requirements in a small area with minimal external components. External programming of clock frequency, current limit, and loop response allows for optimization and flexibility selecting output filter components and transient response. The summing current mode modulator uses lossless current sensing for current feedback and over-current, and includes voltage feedforward. Fairchild’s advanced BiCMOS power process, combined with a thermally efficient MLP package, provides low-RDS(ON), internal MOSFETs, and the ability to dissipate high power in a small package. Under-voltage, thermal shutdown, and power-good are blanked at start-up, but protect the device from damage during fault conditions.
