Product Brief:
The MCP16411 is a Boost regulator from the MCP1641X family of low quiescent current boost converters with integrated status indicators and wide input voltage range for a variety of battery powered applications. The regulator provides an automatic input-to-output voltage bypass operation which help in optimizing battery utilization and achieving high efficiency while fresh batteries’ nominal voltage is in the same range with the converter’s output value.
The MCP16411 use an automatic switchover from PWM to PFM mode for light load conditions, to maximize efficiency over a wide range of output current. The device can be powered by either single-cell, two-cell alkaline/NiMH batteries or single-cell Li-Ion/Li-Polymer batteries. A low-voltage designed architecture allows the regulator to start up without high inrush current or output voltage overshoot from a low input voltage. The start-up voltage is easily programmed by a resistive divider connected to the UVLO pin. If the resistive divider is not used, the default start-up voltage will be 0.85V. The 0.8V built-in UVLOSTOP helps prevent deep discharge of the alkaline battery, which may cause battery leakage. An open-drain Low Battery Output (LBO) pin will warn the user to replace the battery if the input voltage ramps down to the programmed UVLOSTART value.
The MCP16411 includes an additional feature to a low-voltage boost converter for safety: Over-temperature Output. Devices, such as personal care products, Bluetooth headsets or toys, will benefit from combined Power Good and Die Overtemperature (PGT) output, which flags a warning signal when the output level drops below 10% of its nominal value or the die temperature exceeds the factory programmed temp (75°C default). Both functions are implemented in the device on the same PGT pin.
The device also incorporates an output auto-discharge feature. While in shutdown, the device will automatically discharge the output capacitor using an internal switch.
