EVALUATION KIT AVAILABLE  
MAX16922  
2.2MHz, Dual, Step-Down DC-DC  
Converters, Dual LDOs, and RESET  
General Description  
Benefits and Features  
● 1.2A High-Efficiency 2.2MHz DC-DC Converter  
• 3.7V to 28V Operating Supply Voltage  
• 45V Load-Dump Protection  
The MAX16922 power-management integrated circuit  
(PMIC) is designed for medium power-level automotive  
applications and integrates multiple supplies in a small  
footprint. The device includes one high-voltage step-  
down converter (OUT1) and three low-voltage cascaded  
DC-DC converters (OUT2, OUT3, OUT4). OUT1 and  
OUT2 are step-down DC-DC converters, and OUT3/  
OUT4 are linear regulators. The device also includes  
a reset output (RESET) and a high-voltage-compatible  
enable input (EN).  
• Output Voltage: 3.0V to 5.5V  
● 600mA High-Efficiency 2.2MHz DC-DC Converter  
• 2.7V to 5.5V Supply Voltage  
• Output Voltage: 1.0V to 3.9V  
• 180° Out-of-Phase Operation  
• Forced-PWM and Auto-PWM Modes  
● LDO Linear Regulators  
The 1.2A output high-efficiency, step-down DC-DC con-  
verter (OUT1) operates from a voltage up to 28V con-  
tinuous and is protected from load-dump transients up to  
45V. The 600mA output high-efficiency step-down DC-DC  
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.  
• OUT3: 1.0V to 4.15V at 300mA  
• OUT4: 1.0V to 4.15V at 300mA  
• Separate Inputs for Increased Efficiency  
● Enable Input  
● RESET Output Monitoring on OUT1 and OUT2  
● Overtemperature and Short-Circuit Protection  
● Available in  
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.
