It uses DCS-Control topology for fast transient response and seamless PWM\/power-save mode transitions. The input range is 2.5V to 5.5V and the output is adjustable from 0.6V to 5.5V via an external resistor divider. A MODE pin selects between 1.5MHz and 2.5MHz switching frequency, allowing the designer to trade off inductor size versus efficiency. The 15\u00b5A quiescent current and 0.5\u00b5A shutdown current maximize battery life in always-on portable devices. The 100% duty cycle mode maintains output regulation when VIN approaches VOUT, useful during battery discharge. The tiny SOT-563-6 package (1.6 x 1.2mm) minimizes board area in space-constrained wearables and IoT devices.","working_principle":"The TLV62569 uses DCS-Control (Direct Control with Seamless transition), a proprietary topology combining voltage-mode and current-mode regulation. In PWM mode, the device switches at the selected frequency (1.5MHz or 2.5MHz) with synchronous rectification for high efficiency. When the load drops below the power-save threshold, the device seamlessly enters PFM mode, skipping switching cycles to maintain regulation with minimal switching losses and 15\u00b5A IQ. The 100% duty cycle mode turns the high-side FET on continuously when VIN drops close to VOUT, functioning as a low-dropout pass switch. The power good comparator monitors the FB voltage and de-asserts PG when the output drops below the regulation target. The internal soft start (1ms) limits inrush current during startup.","pin_description":"

      • Li-ion to 1.8V FPGA I\/O Rail:<\/b> Convert a 3.7V Li-ion battery to 1.8V at 2A for an FPGA I\/O bank. Select 2.5MHz (MODE low) to use a tiny 0.47\u00b5H inductor, minimizing solution size. The 15\u00b5A IQ preserves battery life when the FPGA enters sleep mode. The PG output signals the FPGA when the 1.8V rail is stable during power-up sequencing.<\/li>
      • 5V USB to 3.3V:<\/b> Regulate 5V USB power down to 3.3V at 2A for a portable instrument. The 100% duty cycle mode maintains 3.3V output even if the USB voltage drops to 3.4V due to cable resistance. Select 1.5MHz (MODE high) for maximum efficiency. The 0.5\u00b5A shutdown current allows the MCU to disable the converter during deep sleep.<\/li>
      • Wearable 3.3V to 1.2V:<\/b> Generate a 1.2V core rail from a 3.3V system rail in a smartwatch. The 2.5MHz mode uses a 0.33\u00b5H inductor that fits within the watch's height constraint. The 95% efficiency minimizes heat and extends battery life. The 1.6 x 1.2mm SOT-563 package occupies minimal board area.<\/li><\/ul>","alternative_models":"
