The device uses peak current-mode control for simplified frequency compensation and fast transient response. An adjustable switching frequency (50 kHz to 1.5 MHz) enables optimization for efficiency or solution size. Eco-mode pulse skipping maintains high efficiency at light loads by reducing switching losses. The integrated boot recharge diode minimizes external component count. Comprehensive protection features include cycle-by-cycle current limiting, hiccup mode overcurrent protection, thermal shutdown, and overvoltage transition protection.","working_principle":"The TPS54335ADDAR uses a constant-frequency peak current-mode control architecture. The internal oscillator sets the switching frequency based on an external RT resistor. During each switching cycle, the high-side MOSFET turns on and current ramps through the inductor. When the peak current reaches the level set by the error amplifier output, the high-side MOSFET turns off and the low-side MOSFET turns on, allowing inductor current to freewheel. An internal transconductance error amplifier compares the divided output voltage to the 0.8 V reference and generates the COMP control signal. The BOOT pin provides gate drive voltage for the high-side MOSFET via an external bootstrap capacitor. Eco-mode disables the low-side MOSFET switching when the inductor current approaches zero at light loads, reducing switching losses and improving efficiency.","pin_description":"
