Product details
Overview
MCP16414T-I/MN from Microchip Technology is a synchronous boost DC-DC converter with automatic input-to-output bypass mode, designed for battery-powered IoT and portable electronics. It operates from 0.8V to 5.25V input, delivers up to 450 mA at 5.0V output from 3.6V input, features 5 μA quiescent current in PFM mode, 500 kHz fixed-frequency PWM operation, and shutdown current of 2.3 μA - enabling long runtime in single-cell Li-ion or two-cell alkaline/NiMH systems.
For engineers reviewing the MCP16414T-I/MN datasheet, MCP16414T-I/MN pinout, MCP16414T-I/MN application, or MCP16414T-I/MN equivalent, key selection criteria include its auto-bypass capability, low-IQ performance, programmable UVLO/LBO, output discharge option, and compatibility with MSOP-10 and TDFN 3 mm × 3 mm packages.
Technical Context
The MCP16414T-I/MN implements a synchronous rectified boost topology with internal compensation and selectable PWM-only switching at 500 kHz. Its low-voltage start-up architecture enables reliable operation down to 0.8V post-startup, while the automatic bypass function engages when VIN ≥ VOUT − Vdrop, eliminating switching losses and improving efficiency during high-battery conditions.
It integrates programmable undervoltage lockout (UVLO) and Low Battery Output (LBO) signaling, supports output discharge during shutdown, and maintains stable regulation across input transients common in remote controls and Bluetooth headsets powered by fading alkaline cells.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.8V (after startup) to 5.25V - supports single-cell Li-ion (2.7–4.2V), two-cell alkaline/NiMH (1.2–3.2V), and fresh battery bypass scenarios |
| Output Current Capability | >450 mA at 5.0VOUT from 3.6VIN - sufficient for BLE SoCs and sensor hubs requiring regulated 5V rail |
| Quiescent Current | 5 μA typical in PFM mode - extends shelf life and runtime in always-on health monitors |
| Switching Frequency | 500 kHz fixed PWM - enables compact external inductor (1–2.2 μH) and ceramic capacitor selection |
| Shutdown Current | 2.3 μA typical - minimizes battery drain during system sleep in remote controllers |
| Bypass Activation | Automatic VIN-to-VOUT conduction when input voltage approaches or exceeds output setpoint - eliminates switching loss and noise during high-VIN states |
Pinout & Package
Package: 10-lead MSOP (3.0 mm × 4.9 mm) and 10-lead 3 mm × 3 mm TDFN - both RoHS-compliant, thermally enhanced surface-mount options.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 0.8–5.25V; powers internal circuitry and switch driver; connects directly to battery or source |
| VOUT | Regulated output node | Delivers configured output voltage (e.g., 3.3V or 5.0V); supplies load and feedback divider |
| FB | Feedback input | Resistor-divider input for output voltage setting; internal reference = 0.6V |
| EN | Enable control | Active-high logic input; pulls device into shutdown (2.3 μA IQ) when low |
| LBO | Low Battery Output | Open-drain flag asserted when VIN falls below programmable UVLO threshold |
| SW | Switch node | Connects to external inductor and catch diode (or synchronous FET); carries pulsed current |
| GND | Power and signal ground | Common return path for input, output, and IC internals; requires low-impedance PCB plane |
| PGT | Power Good indicator | Open-drain output signaling valid VOUT regulation (typically used for system power sequencing) |
Key Features
| Feature | Design Value |
|---|---|
| Auto Bypass Mode | Enables direct VIN-to-VOUT conduction when input voltage nears or exceeds regulated output, eliminating switching loss and EMI during high-battery operation |
| Programmable UVLO & LBO | Allows precise battery depletion detection and graceful system shutdown before brownout - configurable via external resistor divider |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61291DRVR | Lower IQ (300 nA) but no auto-bypass; fixed 3.3V output only; no LBO/PGT pins | Suitable for ultra-low-power always-on sensors where output voltage is fixed and bypass not required | Select if minimal quiescent current outweighs need for programmable output and battery monitoring |
| MAX17222ELA+T | Higher peak output current (1 A), 1.2 MHz switching, no LBO or output discharge; UVLO fixed at 0.65V | Better for high-current, space-constrained designs needing faster transient response | Choose when >500 mA continuous load or smaller inductor size is critical, and battery flagging is handled externally |
Compared with TPS61291DRVR and MAX17222ELA+T, the MCP16414T-I/MN uniquely combines auto-bypass, dual battery-monitoring flags (LBO/PGT), output discharge, and flexible output programming - making it optimal for cost-sensitive, battery-optimized portable systems requiring full power-path control.

FAQ
What is the minimum input voltage required for MCP16414T-I/MN to start up?
The MCP16414T-I/MN requires a minimum of 0.8V after startup to maintain regulation, but its actual startup voltage is higher - typically ~1.0V under light load with recommended external components. This low-voltage capability allows reliable operation from nearly depleted alkaline or NiMH cells, extending usable battery life in remote controls and portable instruments where the MCP16414T-I/MN serves as the primary power rail generator.
Does MCP16414T-I/MN support adjustable output voltage?
Yes, the MCP16414T-I/MN supports adjustable output voltage via an external resistor divider connected to the FB pin, with an internal reference of 0.6V. Common configurations include 3.3V and 5.0V outputs. The device does not support dynamic voltage scaling - output is set at power-up and remains fixed unless the feedback network is modified externally. This flexibility makes the MCP16414T-I/MN adaptable across multiple portable product variants without changing the IC.
How does the auto-bypass feature improve efficiency in MCP16414T-I/MN?
The auto-bypass feature in MCP16414T-I/MN activates when input voltage approaches or exceeds the regulated output voltage minus conduction drop, enabling direct conduction through internal MOSFETs instead of switching. This eliminates switching losses, gate drive losses, and inductor core/copper losses - boosting efficiency to near 99% in bypass mode. For example, when powering a 3.3V load from a 3.6V Li-ion cell, the MCP16414T-I/MN enters bypass, significantly extending runtime compared to conventional boost-only regulators.
What is the purpose of the LBO pin on MCP16414T-I/MN?
The LBO (Low Battery Output) pin on MCP16414T-I/MN is an open-drain output that asserts low when the input voltage falls below a user-programmed undervoltage threshold. It provides early warning of battery depletion to the system MCU, enabling controlled shutdown or data save before brownout. Unlike generic reset signals, LBO is specifically calibrated for battery voltage decay profiles - a key differentiator in health monitors and remotes where the MCP16414T-I/MN manages end-of-life behavior.
Can MCP16414T-I/MN be used with single-cell Li-ion batteries?
Yes, MCP16414T-I/MN is explicitly qualified for single-cell Li-ion (2.7–4.2V) and Li-Polymer batteries. Its 0.8V–5.25V input range, auto-bypass mode, and 500 kHz PWM operation make it ideal for this use case: bypass engages above ~3.8V to avoid unnecessary switching, while efficient boost operation resumes as the cell discharges below 3.6V. This dual-mode behavior ensures optimal energy extraction from the MCP16414T-I/MN's supported Li-ion sources.
