Product details

Overview

MCP16414-I/MN from Microchip Technology is a synchronous boost DC-DC converter with automatic input-to-output bypass mode, designed for single-cell or two-cell battery-powered systems. It operates from 0.8V (post-startup) to 5.25V input, delivers up to 450 mA output at 5.0V with 3.6V input, achieves 96% peak efficiency, and features 5 µA quiescent current in PFM mode-enabling long runtime in Bluetooth® headsets and remote controllers.

For engineers reviewing the MCP16414-I/MN datasheet, MCP16414-I/MN pinout, MCP16414-I/MN application, or MCP16414-I/MN equivalent, key selection factors include its auto-bypass capability during battery voltage decay, selectable PFM/PWM operation, programmable UVLO/LBO, 500 kHz fixed-frequency PWM mode, and support for MSOP-10 and TDFN 3 mm × 3 mm packages.

Technical Context

The MCP16414-I/MN implements a synchronous rectified boost topology with internal compensation and integrated MOSFETs. Its auto-bypass function engages when input voltage approaches or exceeds regulated output voltage-eliminating switching losses and reducing quiescent current to 2.3 µA in shutdown.

It supports dual operating modes: fixed 500 kHz PWM (enabled via MODE pin) or automatic PFM/PWM transition based on load. Programmable UVLO threshold and Low Battery Output (LBO) provide precise battery monitoring without external components.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	0.8 V (after startup) to 5.25 V - enables direct use with fresh alkaline/NiMH (1–2 cell) or Li-ion (1 cell) batteries without pre-regulation.
Output Current Capability	450 mA @ 5.0 V_OUT, 3.6 V_IN - sufficient to power RF modules and microcontrollers in compact IoT endpoints.
Quiescent Current	5 µA typical in PFM mode - extends shelf life and operational runtime in always-on sensor nodes.
Switching Frequency	500 kHz (PWM mode) - allows use of small, low-profile inductors (e.g., 1–2.2 µH) and ceramic output capacitors.
Bypass Mode Activation	Automatic input-to-output conduction when V_IN ≥ V_OUT - eliminates switching loss and maintains regulation with minimal dropout (< 100 mV typical).
Shutdown Current	2.3 µA typical - preserves battery charge during extended sleep or storage periods.

Pinout & Package

Package: 10-lead MSOP (3.0 mm × 4.9 mm, 0.5 mm pitch) and 10-lead TDFN (3.0 mm × 3.0 mm, 0.5 mm pitch). Both packages are RoHS-compliant and thermally enhanced.

Pin/Terminal	Circuit Role	Design Meaning
VIN	Input supply connection	Accepts 0.8–5.25 V; powers internal circuitry and high-side switch; requires local 1–10 µF ceramic decoupling.
VOUT	Regulated output node	Delivers stable output (programmed via FB resistor divider); connects to output capacitor and load.
SW	Switch node	Drives external inductor; carries pulsed current up to 1 A peak; requires low-inductance layout to minimize EMI.
FB	Feedback input	Sets output voltage via resistive divider (e.g., 1.22 V reference); enables adjustable outputs from 2.0 V to 5.25 V.
EN	Enable control	Active-high logic input; pulls down to disable regulator and engage shutdown mode (I_Q = 2.3 µA).
LBO	Low battery indicator	Open-drain output asserted low when VIN falls below programmed UVLO threshold; drives LED or MCU GPIO.
MODE	Operating mode select	High = fixed 500 kHz PWM; low = automatic PFM/PWM transition for optimal light-load efficiency.
GND	Power and signal ground	Common return for VIN, VOUT, SW, and internal circuits; must be low-impedance plane under IC.

Key Features

Feature	Design Value
Auto-bypass operation	Enables seamless transition from boost to direct conduction when VIN ≥ VOUT, eliminating switching loss and extending usable battery range by up to 15% in Li-ion discharge profiles.
Integrated soft-start	Controls output ramp rate during startup to limit inrush current to < 100 mA, preventing brownout in weak or high-ESR batteries.
Programmable UVLO & LBO	Configurable undervoltage lockout (e.g., 0.9 V–1.8 V) and open-drain LBO signal allow precise battery end-of-life detection without external comparators.
Internal compensation	Eliminates need for external compensation network, reducing BOM count by ≥2 passive components and simplifying layout validation.
Output discharge option	When enabled via EN pin sequence, actively discharges VOUT capacitor during shutdown-preventing residual voltage from interfering with system reset sequencing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar boost converter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Texas Instruments TPS61291DRVR	Fixed 1.2 MHz switching frequency; no auto-bypass; 3.5 µA I_Q; requires external LBO comparator.	Lacks seamless transition at V_IN ≈ V_OUT; better suited for constant-V_IN applications like USB-powered accessories.	Select when higher switching frequency justifies smaller magnetics and auto-bypass is unnecessary.
Analog Devices ADP5070ACPZ-R7	Higher 2.5 A switch current; dual-output capability; 2.5 µA I_Q; no integrated LBO or UVLO programming.	Designed for precision analog rails; lacks battery-aware features like programmable LBO or soft-start tailored for primary cells.	Prefer for multi-rail industrial sensors where output flexibility outweighs battery optimization.

Compared with TPS61291DRVR and ADP5070ACPZ-R7, the MCP16414-I/MN uniquely combines auto-bypass, programmable battery monitoring, and ultra-low quiescent current in a single-channel boost architecture-making it the only choice for cost-sensitive, battery-limited consumer and medical wearables requiring maximum energy extraction per cell.

FAQ

What is the minimum input voltage required for startup of the MCP16414-I/MN?

The MCP16414-I/MN starts up from an input voltage as low as 0.8 V after initial biasing. This ultra-low startup threshold enables operation directly from deeply discharged alkaline or NiMH cells, and supports cold-start functionality in energy-harvesting systems where ambient power sources deliver marginal voltage. The internal charge pump and low-threshold MOSFETs ensure reliable initiation even at room temperature and light loads.

Does the MCP16414-I/MN support adjustable output voltage, and how is it configured?

Yes, the MCP16414-I/MN supports adjustable output voltage from 2.0 V to 5.25 V using an external resistor divider connected to the FB pin. The internal reference is 1.22 V ±1.5%, and standard configurations use a 100 kΩ top resistor with values scaled per desired V_OUT. For example, setting V_OUT = 3.3 V requires R1 = 100 kΩ and R2 = 58.2 kΩ. No additional compensation components are needed due to internal compensation.

How does the auto-bypass feature of the MCP16414-I/MN improve system-level battery utilization?

The auto-bypass feature in the MCP16414-I/MN activates when input voltage rises to within ~50 mV of the regulated output voltage, enabling direct conduction between VIN and VOUT. This eliminates switching losses and reduces quiescent current to near-shutdown levels while maintaining regulation-extending usable battery capacity by up to 15% in single-cell Li-ion applications and improving effective discharge curve flatness in alkaline systems.

What is the purpose of the MODE pin on the MCP16414-I/MN, and what are its valid states?

The MODE pin on the MCP16414-I/MN selects between two operating modes: logic-high enables fixed 500 kHz PWM operation for predictable EMI and consistent transient response; logic-low enables automatic PFM/PWM mode that transitions seamlessly based on load current to maximize light-load efficiency. The pin is CMOS-compatible and must be pulled to VIN or GND with ≤100 kΩ; floating is not allowed.

Can the MCP16414-I/MN be used with lithium primary batteries such as CR2032, and what design considerations apply?

Yes, the MCP16414-I/MN is compatible with CR2032 and other lithium primary batteries. Key considerations include configuring UVLO to ~2.0 V to avoid premature cutoff, selecting an output voltage ≤3.3 V to maintain margin above battery's nominal 3.0 V, and verifying inductor DCR < 150 mΩ to minimize dropout in bypass mode. The 5 µA quiescent current ensures < 0.5% annual self-discharge-critical for 10-year shelf-life designs using MCP16414-I/MN.
