Torex XC9276
Ultra-Low Quiescent Current, Synchronous Step-Down PFM DC/DC Converter with Output voltage selectable function
Overview
| Topology | Buck Converter |
| Input voltage | 1.8-6 V |
| Output 1 | 3.6 V / 0.15 A |
Description
The XC9276 Series is a 150mA step-down synchronous rectification DC/DC converter which has an output voltage switchover function with an ultra-low power consumption circuit and a PFM control. The efficiency performance at a light load current is dramatically improved by implementing ultra-low power consumption circuits which has 200nA consumption current, and PFM control method. Additionally two-preset output voltage switchover function is available with using VSET pin. This function can select an appropriate output voltage based on the MCU behavior mode and contribute a power consumption reduction for a total system. Due to these functions, XC9276 series are suitable for equipment which needs a high efficiency performance at a light load current, and a long-time battery life. XC9276 series are compatible to 2.2uH inductor therefore it can reduce an output ripple voltage which is a negative side of PFM control method, and a PCB board area size..
