It integrates 12m\u03a9 (low-side) and 18m\u03a9 (high-side) MOSFETs for 94.7% efficiency at 3.6V-to-5V\/3A conversion. The 8A valley current limit supports high output power from low-voltage sources. A MODE pin selects between auto PFM mode (26\u00b5A IQ for light-load efficiency) and forced PWM mode (for predictable noise spectrum). The device features true load disconnect during shutdown (no body diode path from output to input), pass-through mode when VIN exceeds VOUT, 5.7V output overvoltage protection, and output short-circuit protection \u2014 all in a tiny 2x2mm VQFN-7 package.","working_principle":"The TPS61022 uses a synchronous boost (step-up) topology with current-mode control. During each switching cycle, the low-side MOSFET turns on, building current in the external inductor. When the inductor current reaches the valley current limit threshold, the low-side FET turns off and the high-side FET turns on, transferring the inductor energy to the output. The switching frequency is nominally 1MHz when VIN > 1.5V and decreases to 0.6MHz as VIN drops below 1V, maintaining manageable on-times at low input voltages. In auto PFM mode, the device skips pulses at light load to maintain regulation with minimal switching losses (26\u00b5A IQ). In forced PWM mode, the device switches continuously regardless of load. When VIN rises above VOUT, the pass-through mode turns on the high-side FET continuously, connecting VIN to VOUT through the inductor with very low voltage drop \u2014 useful when a primary supply is available. True disconnect is achieved because the high-side MOSFET has no body diode path from VOUT to VIN when the device is shut down.","pin_description":"

      • Supercapacitor Backup Power:<\/b> Use a 2.7V supercapacitor as backup for a 3.3V or 5V system rail. When the main supply fails, the TPS61022 boosts the supercap voltage from 2.7V down to 0.5V, extracting maximum stored energy. The 0.5V minimum input allows the supercap to discharge to near-zero, extending backup time. Set MODE low (auto PFM) to minimize IQ during normal operation when the main supply is present and the TPS61022 is not switching.<\/li>
      • USB Power Bank (5V\/2A):<\/b> Boost a single Li-ion cell (3.0V-4.2V) to 5V\/2A for USB output. The 8A current limit supports 2A output even at 3.0V input. True disconnect prevents battery drain when the USB load is removed. The 94.7% efficiency minimizes heat in the compact enclosure.<\/li>
      • GPRS Module Power:<\/b> Supply a GPRS module that draws 2A bursts during transmission. The TPS61022 boosts a single LiFePO4 cell (3.2V) to 4.0V with 8A current limit, handling the 2A transmit bursts with margin. Forced PWM mode ensures a clean output voltage without PFM ripple during the critical transmit windows.<\/li><\/ul>","alternative_models":"
