Renesas | ISL9122AIIN-EVZ

Renesas has introduced the ISL9122, a family of flexible buck-boost switching regulators which draws ultra-low quiescent current. This makes them ideal for use in powering sensors, microcontrollers, wireless devices and other system components which normally operate intermittently, with long periods in standby mode.

APPLICATIONS
• Wireless earbuds
• Fitness bands
• Smart watches
• Water or gas meters
• Portable medical devices
• Battery-operated smart IoT devices

FEATURES
• High efficiency:
• 84% at light load of 10μA
• 97% peak efficiency at full load
• Automatic and selectable forced bypass power-saving mode
• Adjustable output-voltage range: 1.8V to 5.375V in 25mV increments
• 500mA maximum output current
• Only requires three external components: one inductor, and input and output capacitors
• Protection functions:
• Over-current
• Short-circuit
• Over-temperature
