SIMO-3O-LS-T22ULL-1.62-3.63-0.6-2.2.01_TSMC_22_ULL is a 3-output Single Inductor Multiple Output (SIMO) DC/DC buck converter in TSMC 22ULL.
Key Benefits
- Multi-rail efficiency: Power up to 3 independent domains with a single inductor ? reducing size, cost, and design complexity.
- Ultra-low BoM cost: Just one compact 1 µH inductor to generate up to four distinct regulated outputs.
- Design flexibility: Each output voltage is individually programmable, enabling fine-tuned adaptation to SoC or subsystem requirements.
- Maximized battery life:
- o Active mode: High conversion efficiency ensures longer operation per charge.
- o Standby mode: Industry-leading ultra-low quiescent current extends battery runtime in sleep states.
- Compact & cost-optimized: Ideal for space-constrained designs in wearables, IoT, and portable electronics.
- System integration ready: Supports dynamic voltage scaling to match SoC power states.
- Green & efficient: Reduces energy waste, enabling eco-friendly low-power designs.
