The COT control architecture with HyperLight Load® mode provides very high efficiency at light loads, while still having an ultra-fast transient response. The MIC33M650 output voltage is set by two VSEL (Voltage Selection) pins, between nine different values. This method eliminates the need for an external feedback resistor divider and improves the output voltage setting accuracy. The 2.4V to 5.5V input voltage range, low shutdown and quiescent currents make the MIC33M650 ideal for single-cell Li-Ion battery-powered applications. The 100% duty cycle capability provides low dropout operation, extending operating range in portable systems. The MIC33M650 pinout is compatible with the MIC33M656 I2C-based programmable regulator version, such that applications can be easily converted. An open-drain PG output is provided to indicate when the output voltage is within 9% of regulation and facilitates the interface with an MCU or power sequencing. If set in shutdown (EN = GND), the MIC33M650 typically draws 1.5 µA, while the output is discharged through 10pull-down. The MIC33M650 is available in a thermally efficient, 53-Lead, 6 mm x 10 mm x 3 mm B1QFN package, with an operating junction temperature range from -40°C to +125°C.
