This high-performance, fixed frequency, current-mode PWM step-up DC/DC converter efficiently produces 12V from input voltages between 3.6V to 5.5V. The project is built using the PAM2423 chip, which includes an integrated power MOSFET that supports a peak current of up to 5.5A. The IC utilizes simple external loop compensation allowing optimization between component size, cost, and AC performance across a wide range of applications. Additional functions include an externally programmable soft-start function for easy inrush current control, internal over-voltage protection (OVP), cycle-by-cycle current limit protection, under-voltage lock-out, and thermal shutdown.
