Key Features
- 2 MHz switching frequency reduces inductor and capacitor size, enabling ultra-compact power supply layouts
- Automatic PWM/PFM mode switching maintains high efficiency from light loads up to 500 mA full-load output current
- Wide input range of 2.7 V to 5.5 V makes the MCP1602-330I/MS compatible with single-cell Li-ion and 3.3 V/5 V rail applications
Applications
The MCP1602-330I/MS is ideal for battery-powered portable devices such as handheld instruments, IoT sensor nodes, and Bluetooth modules that require a regulated 3.3 V rail from a single-cell Li-ion battery. Its PFM mode and 2 MHz operation allow designers to use tiny passives while preserving battery life. Industrial microcontroller supply circuits and wearable electronics also benefit from its small 8-pin MSOP footprint and wide input voltage range.

Frequently Asked Questions
How does the MCP1602-330I/MS achieve high efficiency at light loads in battery-powered IoT designs?
The MCP1602-330I/MS automatically transitions from PWM to PFM (Pulse Frequency Modulation) mode at light loads, reducing switching losses. This dual-mode control lets the device maintain efficiency well above 80% even at currents below 50 mA, significantly extending battery life in IoT sensor nodes powered by a single-cell Li-ion source at 3.7 V.
What input voltage range does the MCP1602-330I/MS support, and which battery chemistries does that cover?
The MCP1602-330I/MS accepts input voltages from 2.7 V to 5.5 V. This range covers single-cell Li-ion batteries (3.0 V to 4.2 V), alkaline AA packs (two cells at 2.4 V to 3.2 V — marginal), and 3.3 V or 5 V system rails, making it versatile for portable and embedded power applications.
Why does a 2 MHz switching frequency matter when selecting external inductors for the MCP1602-330I/MS?
At 2 MHz, the required inductance drops to roughly 1 µH to 4.7 µH versus 10 µH to 47 µH at 300 kHz, allowing compact 0402 or 0603 inductors to be used. This directly reduces PCB area and bill-of-materials cost in space-constrained wearable or handheld designs while maintaining a 500 mA output current capability.
For a compact PCB layout, how many pins does the MSOP-8 package of the MCP1602-330I/MS expose, and what is its approximate footprint?
The MSOP-8 package provides 8 pins with a body size of approximately 3 mm × 3 mm and 0.65 mm pin pitch. This small footprint is significantly more compact than standard SOIC-8 packages, freeing board space in handheld instruments and wearable devices running from a 3.3 V to 5 V power rail.
