The 1.2A output high-efficiency, step-down DC-DC converter (OUT1) operates from a voltage up to 28V continuous and is protected from load-dump transients up to 45V. The 600mA output high-efficiency step-down DCDC converter (OUT2) runs from a voltage up to 5.5V. The two 300mA LDO linear regulators offer low dropout of only 130mV (typ). The power-good RESET output provides voltage monitoring for OUT1 and OUT2. OUT1 and OUT2 use fast 2.2MHz PWM switching and small external components. The high-voltage converter (OUT1) enters skip mode automatically under light loads to prevent an overvoltage condition from occurring at the output. The low-voltage synchronous DC-DC converter (OUT2) can operate in forced-PWM mode to prevent any AM band interference or high-efficiency auto-PWM mode. |
