AEC-Q100 Grade 1 qualified, it operates from a 2.25 V to 6 V input and delivers up to 1.5 A output current with adjustable output voltage from 0.6 V to VDD. The 3.5 MHz fixed switching frequency allows the use of a tiny 1 \u00b5H chip inductor and small ceramic capacitors, minimizing solution footprint. The device automatically transitions between PWM mode for heavy loads and PFM (power-save) mode for light loads, maintaining high efficiency across the full load range. The 100% duty cycle mode enables the lowest possible dropout voltage when the input approaches the output. The 1 \u00b5A shutdown current preserves battery life in always-on automotive systems.","working_principle":"The TPS62290TDRVRQ1 is a current-mode synchronous buck converter with integrated N-channel MOSFET switches. At moderate to heavy loads, the device operates in fixed-frequency PWM mode at 3.5 MHz, where the peak inductor current is controlled cycle-by-cycle through the error amplifier output. At light loads, the device enters power-save mode (PFM), where switching pulses are generated only when the output voltage drops below the threshold, skipping pulses to minimize switching losses and maintain high efficiency. The transition between modes is automatic and seamless. The 100% duty cycle mode turns on the high-side switch continuously when the input voltage drops close to the output, effectively operating as a pass-through switch. The internal soft-start limits inrush current during startup. Thermal shutdown and current limit protection ensure safe operation under fault conditions.","pin_description":"
