Key Features
- Current-mode PWM control with 2.7 V to 5.5 V input range supporting single-cell Li-ion and dual-cell alkaline boost designs
- Integrated power-good (PGOOD) output flag for system sequencing and fault detection
- 2 V UVLO threshold prevents operation below minimum input voltage, protecting the battery from deep discharge
- Compact MSOP-8 package minimizes PCB area in space-constrained portable and wearable power supply designs
Applications
The MCP1652R-E/MS is designed for portable battery-powered boost converters where a single-cell Li-ion or two-cell alkaline battery must be stepped up to 5 V or higher system rails. Its PGOOD output flag enables power sequencing in multi-rail systems, signaling downstream processors to begin initialization only after the boost rail reaches regulation. The current-mode PWM architecture provides fast transient response and inherent cycle-by-cycle current limiting in medical devices, wireless sensors, and handheld instruments requiring up to several hundred milliwatts of output power.

Frequently Asked Questions
What input voltage range does MCP1652R-E/MS support and which battery chemistries does that cover?
The MCP1652R-E/MS accepts input voltages from 2.7 V to 5.5 V, covering single-cell Li-ion batteries (discharged at 2.7 V to fully charged at 4.2 V) and dual-cell alkaline or NiMH packs (from 1.8 V to 3 V nominal). The 2 V UVLO threshold prevents boost operation when the battery is too deeply discharged to support reliable regulation.
How does the PGOOD flag on MCP1652R-E/MS improve system startup reliability?
The PGOOD open-drain output asserts high only when the boost output voltage reaches the regulation target (typically within 3%), allowing downstream digital logic or processors to remain in reset until power is stable. In a 5 V boosted rail powering a microcontroller, this prevents data corruption and brownout faults that occur when the processor powers up before the supply reaches 4.75 V minimum.
What control topology does MCP1652R-E/MS use and why does current mode matter for inductor selection?
The MCP1652R-E/MS uses current-mode PWM control, which senses peak inductor current each switching cycle to determine the duty cycle. This topology provides inherent cycle-by-cycle overcurrent protection limiting peak current regardless of inductor tolerance, and simplifies inductor selection since the converter remains stable with a wider range of inductance values (typically 4.7 µH to 22 µH) compared to voltage-mode controllers.
For a wearable device design, how does the MSOP-8 package of MCP1652R-E/MS compare in size to SOIC-8?
The MSOP-8 package occupies approximately 3 mm × 3 mm, roughly 60% less PCB area than a standard SOIC-8 footprint at 5 mm × 4 mm. In wearable health monitors or hearing aids where total PCB area may be under 400 mm², using MSOP-8 packaging saves valuable real estate compared to SOIC variants without requiring a different schematic or external component count.
