Microchip Technology, Inc. Voltage Regulators - DC DC Switching Regulators MIC23156-0YML-T5

The MIC23156-0YML-T5 is a synchronous buck regulator designed for high efficiency and dynamic voltage scaling. It operates with an input voltage range of 2.7V to 5.5V and can deliver up to 1.5A of output current. The output voltage is adjustable from 0.7V to 2.4V in 10 mV steps, controlled via I¬=C, allowing for precise voltage management suitable for processor core supplies. This regulator features a HyperLight Load mode that enhances efficiency at light loads and provides fast transient response. It has a low quiescent current of 30 ¬µA when not switching, which is beneficial for battery-powered applications. The device includes thermal shutdown and current-limit protection, ensuring safe operation under various conditions. The MIC23156-0YML-T5 is available in a compact 17-pin QFN package, making it suitable for space-constrained designs. It is stable with a 1 ¬µH output inductor and a 2.2 ¬µF ceramic capacitor, contributing to a small overall solution size. The device operates over a junction temperature range of -40¬8C to +125¬8C, making it versatile for various applications, including mobile handsets and solid-state drives.
