Introduction
The MAX20048 is a current-mode buck-boost controller. The device operates with input voltages from 4.5V to 36V while using only 55μA quiescent current at no load. Once the startup conditions are satisfied, the device can operate over an extended input voltage range of 2V to 36V. The switching frequency is resistor programmable from 220kHz to 2.2MHz and can be synchronized to an external clock. The device output voltage is available as 5V fixed or adjustable from 4V to 25V. The wide input voltage range, along with its ability to maintain constant output voltage during battery transients, makes the devices ideal for automotive applications. In light-load applications, a logic input (FSYNC) allows the devices to operate either in skip mode for reduced current consumption, or fixed-frequency, forced-PWM mode to eliminate frequency variation and help minimize EMI. Protection features include cycle-by-cycle current limit followed by hiccup during sustained overloads, input under-voltage lockout (UVLO), output overvoltage protection and thermal shut-down with automatic recovery. The MAX20048 is a current-mode buck-boost H-bridge controller. Based on the input and output voltage of the application, the controller operates in buck or boost mode and transitions seamlessly between these modes to maintain a constant output voltage. The architecture consists of a peak-current-mode control loop that senses the inductor current using an external current-sense resistor.
