Frequently Asked Questions
What is the input and output voltage of the MCP1602-180I/MS?
The MCP1602-180I/MS accepts an input voltage from 2.7 V to 5.5 V and provides a fixed 1.8-V output. This covers single-cell Li-ion batteries (down to approximately 3 V), USB 5-V supplies, and two-cell alkaline battery packs within a single design.
What is the maximum output current of the MCP1602-180I/MS?
The device can supply a continuous output current of up to 500 mA. The synchronous rectification topology achieves this without requiring an external Schottky diode, reducing component count and improving efficiency at moderate to heavy loads.
What switching frequency does the MCP1602-180I/MS operate at?
It operates at a fixed 2-MHz switching frequency, which is significantly higher than traditional 300-kHz to 600-kHz buck regulators. This allows the use of a small 1-µH to 2.2-µH inductor and ceramic output capacitors, shrinking the overall power supply footprint.
What control modes does the MCP1602-180I/MS support?
The device supports both PWM (Pulse Width Modulation) and PFM (Pulse Frequency Modulation) control modes. It automatically transitions to PFM at light loads to reduce switching losses and extend battery life, then returns to PWM at heavier loads for tighter output voltage regulation.
What package does the MCP1602-180I/MS come in and is it RoHS compliant?
It is available in an 8-pin MSOP (Mini Small Outline Package) with a body width of approximately 3 mm, offering a very small solution size. The Pb-free code is 'Yes', confirming RoHS compliance, making it suitable for products sold in regulated markets worldwide.
