SL2188A28XG DC-DC Regulator SOT-23
SL2188 series is a CMOS, low-quiescent-current, PFM-type synchronous rectifier DC-DC boost converter. It features advanced low-noise design and high efficiency, making it ideal for battery-powered portable electronics. The SL2188A28XG model provides a fixed 2.8V output without CE enable control.
Our Advantages
- Ultra-low quiescent current (15μA typical) greatly extends battery life
- Low-noise PFM control reduces interference to surrounding circuits
- Wide input voltage from 0.9V works with 1–3 cell batteries
- High output accuracy ±2.5% ensures stable system performance
- Very simple external circuit, easy to design and mass-produce
- Multiple miniature packages fit compact portable devices
- Built-in synchronous rectifier for high conversion efficiency
