It employs TI's D-CAP2 control mode, which provides fast transient response and supports low-ESR output capacitors such as specialty polymer and ceramic types without requiring external compensation components. The device operates in Advanced Eco-mode to maintain high efficiency during light-load conditions, with a quiescent current of only 230 \u00b5A. Integrated 122 m\u03a9 and 72 m\u03a9 MOSFETs enable efficient power delivery from a 4.5V to 17V input to an adjustable output from 0.76V to 7V at up to 2A.","working_principle":"The TPS562200 uses the D-CAP2 (Direct Capacitor-Area Proportional 2) control architecture, which is a pseudo-fixed-frequency adaptive on-time control scheme. The internal on-time timer sets the high-side MOSFET on-duration proportional to the input voltage and inversely proportional to the output voltage, maintaining a near-constant 650 kHz switching frequency. The output voltage is sensed through a feedback resistor divider and compared against an internal 0.76V reference. When the feedback voltage falls below the reference, a new on-time pulse is initiated. An internal ripple injection network eliminates the need for large output capacitance with high ESR, allowing the use of all-ceramic output capacitors. The Eco-mode operation disables switching when the output voltage is above the set point at light loads, skipping pulses to reduce switching losses and maintain high efficiency.","pin_description":"
