At medium to heavy loads, the device operates in
pulse width modulation (PWM) mode with 1.5-MHz
switching frequency. At light load, the device
automatically enters Power Save Mode (PSM) to
maintain high efficiency over the entire load current
range. In shutdown, the current consumption is
reduced to less than 2 μA.
The TLV62569 provides an adjustable output voltage
via an external resistor divider. An internal soft start
circuit limits the inrush current during startup. Other
features like over current protection, thermal
shutdown protection and power good are built-in. The
device is available in a SOT23 and SOT563 package.
