What are the key features of MCP1652S-E/MS?
- 750 kHz PWM switching frequency enabling use of small inductors and capacitors, reducing total solution size in portable and IoT boost converter designs
- Current-mode control architecture providing inherent cycle-by-cycle overcurrent protection and fast transient response across a 2.7 V to 5.5 V input range
- 8-pin MSOP package occupying minimal PCB area, ideal for space-constrained single-cell Li-ion battery boost applications
What is MCP1652S-E/MS used for?
The MCP1652S-E/MS is designed for boost converter applications in handheld devices, wireless IoT nodes, and portable medical instruments powered from single-cell Li-ion or AA batteries where the system rail must be stepped up from 2.7 V to 5.5 V to a higher regulated voltage. Its 750 kHz switching frequency allows designers to use smaller passive components, shrinking the overall power supply footprint. The current-mode PWM control delivers stable regulation and fast load transient response suitable for sensitive RF and analog subsystems.

Frequently Asked Questions
What switching frequency does MCP1652S-E/MS operate at, and how does this affect the size of external passive components?
The MCP1652S-E/MS operates at a fixed 750 kHz switching frequency. This high frequency allows the use of inductors in the 1 µH to 4.7 µH range and ceramic output capacitors as small as 4.7 µF, significantly reducing the physical size of the boost converter compared to lower-frequency controllers that require larger inductors and electrolytic capacitors.
Which input voltage range does MCP1652S-E/MS support, and how does this map to common battery chemistries?
The MCP1652S-E/MS accepts input voltages from 2.7 V to 5.5 V. This range covers the full discharge curve of a single-cell Li-ion battery (3.0 V to 4.2 V), two-cell NiMH packs (2.4 V to 3.0 V), and regulated 3.3 V system rails, making it a versatile boost front-end for portable consumer, medical, and industrial IoT applications.
How does current-mode control in MCP1652S-E/MS benefit designs requiring tight output regulation under rapidly changing loads?
Current-mode control in the MCP1652S-E/MS senses inductor current on a cycle-by-cycle basis, enabling the controller to respond to load transients within a single switching cycle of 1.33 µs. This results in tighter output voltage regulation and faster recovery compared to voltage-mode control, which is critical in RF transmitters and microcontroller loads that switch between sleep and active states rapidly.
For a compact wearable PCB design, what board area advantage does the MCP1652S-E/MS MSOP-8 package offer compared to a SOIC-8 alternative?
The 8-pin MSOP package of the MCP1652S-E/MS measures approximately 3 mm x 3 mm with a 0.65 mm lead pitch, occupying roughly 40% less PCB area than a standard SOIC-8 footprint (approximately 5 mm x 4 mm). This size reduction is significant for wearable devices and compact IoT modules where PCB real estate is at a premium and component density must be maximized.
