MAX42402
Description
The MAX42402/MAX42403 IC are a tiny synchronous buck converter with integrated high-side and low-side switches. The MAX42402/MAX42403 are designed to deliver up to 2.5A/3.5A with a wide, 4.5V to 36V input voltage range. Voltage quality can be monitored by observing the PGOOD signal. The IC can operate in dropout by running at 99% duty cycle, making it ideal for industrial applications.
The MAX42402/MAX42403 offer externally programmable output voltage. Fixed internal frequency options of 1.5MHz/400k Hz are available, which allow for small external ponents and reduced output ripple.
When SYNC is low, the MAX42402/MAX42403 automatically enter skip mode at light loads with an ultralow quiescent current of 27u A at no load. A pinselectable forced-PWM mode is also available, which helps to improve EMI performance. The devices have a spread-spectrum frequency modulation option designed to minimize EMI-radiated emissions due to the modulation frequency.
