GENERAL 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.
