Analog Devices ADPL76030

Description

The ADPL76030 is a synchronous 4-switch buck-boost DC/DC controller that regulates output voltage, and input or output current from an input voltage above, below, or equal to the output voltage. The proprietary peak-buck, peak-boost current-mode control scheme allows adjustable and synchronizable 600 kHz to 1.4 MHz fixed frequency operation, or internal 25% triangle spread spectrum frequency modulation for low EMI. With a 4 V to 55 V input voltage range, 0 V to 55 V output voltage capability, and seamless low noise transitions between operation regions, the ADPL76030 is ideal for voltage regulators, and battery and supercapacitor charger applications in automotive, industrial, telecom, and even battery-powered systems.The ADPL76030 provides input or output current monitor and power good flag. Fault protection is also provided to detect output short-circuit condition, during which the ADPL76030 retries, latches off, or keeps running.
