Product details
Overview
MCP16411T-I/MN from Microchip Technology is a synchronous boost DC-DC converter with automatic input-to-output bypass mode, designed for ultra-low-quiescent-current battery-powered systems. It operates from 0.8V (post-startup) to 5.25V input, delivers up to 450 mA at 5.0V output from 3.6V input, and features 5 µA typical quiescent current in PFM mode-enabling long runtime in Bluetooth® headsets and single-cell IoT sensors.
For engineers reviewing the MCP16411T-I/MN datasheet, MCP16411T-I/MN pinout, MCP16411T-I/MN application, or MCP16411T-I/MN equivalent, key selection criteria include its auto-bypass capability, 2.3 µA shutdown current, selectable PFM/PWM operation, integrated UVLO/LBO, and support for MSOP-10 and TDFN 3×3 mm packages.
Technical Context
The MCP16411T-I/MN implements a synchronous rectified boost topology with internal compensation and programmable undervoltage lockout (UVLO). Its auto-bypass function engages when VIN ≥ VOUT − 100 mV, eliminating switching losses and enabling >96% efficiency in fresh-battery conditions.
It supports automatic PFM/PWM mode transition, maintains stable regulation down to 0.8V input after startup, and integrates output discharge during shutdown-critical for low-power remote controllers and health-monitoring wearables requiring clean power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.8 V (after startup) to 5.25 V - enables direct operation from single Li-ion (3.0–4.2 V) or two alkaline/NiMH (1.2–3.0 V) cells. |
| Quiescent Current | 5 µA typical (PFM mode) - extends battery life in always-on sensor nodes and wearable health devices. |
| Peak Input Current Limit | 1 A typical - sustains reliable start-up and transient response under load without brownout in portable instruments. |
| Output Current Capability | 450 mA @ 5.0 VOUT, 3.6 VIN - sufficient to power BLE SoCs and RF front-ends in compact IoT endpoints. |
| Bypass Threshold | Auto-engages when VIN ≥ VOUT − 100 mV - eliminates switching loss and noise during high-battery-voltage operation. |
| Shutdown Current | 2.3 µA typical - ensures minimal battery drain during extended standby in remote controls. |
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 suitable for space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 0.8–5.25 V; powers internal circuitry and switch driver; requires local ceramic decoupling. |
| VOUT | Regulated output node | Delivers boosted voltage; connects to output capacitor and load; bypass path routes directly from VIN when enabled. |
| SW | Switch node | Drives external inductor; carries high di/dt; must be routed with minimal loop area to reduce EMI. |
| FB | Feedback input | Sets output voltage via resistor divider; internal reference is 0.6 V; supports adjustable or fixed-output configurations. |
| EN | Enable control | Active-high logic input; pulls to GND to disable regulator and engage shutdown mode (2.3 µA IQ). |
| LBO | Low battery indicator | Open-drain output asserts low when VIN drops below programmable UVLO threshold-used for system-level battery monitoring. |
| PGT | Power good flag | Open-drain output signals valid regulation (VOUT within ±5%); enables sequencing with MCU or PMIC. |
| DIS | Output discharge enable | When asserted, activates internal FET to discharge VOUT capacitor-prevents residual voltage in shutdown state. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic input-to-output bypass | Eliminates switching loss and EMI when VIN approaches or exceeds VOUT-extends usable battery range by up to 15% in single-cell Li-ion applications. |
| Programmable UVLO & LBO | Allows precise battery depletion management: UVLO prevents startup below safe voltage; LBO provides early warning before cutoff. |
| Integrated output discharge (DIS) | Removes stored charge from output cap on shutdown-ensures safe reset and meets IEC 62368-1 touch-safety requirements. |
| Soft-start circuitry | Controls ramp rate of VOUT at startup-limits inrush current to protect weak batteries and avoid system brownout in remote controllers. |

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 3.3 V output; no auto-bypass; 3.5 µA IQ; 1.8–5.5 V input | Lacks input-to-output bypass and programmable LBO; better suited for fixed-VOUT, low-cost remote controls | Select when fixed output and lowest possible quiescent current outweigh need for battery-range optimization. |
| Analog Devices ADP5070ACPZ-R7 | Adjustable output; 2.5 MHz switching; no auto-bypass; 2.5 µA IQ; 2.85–15 V input | Higher input range and frequency; unsuitable for sub-1V startup or single-cell alkaline use | Prefer for higher-VIN industrial sensors where fast transient response matters more than ultra-low-IQ battery life. |
Compared with TPS61291DRVR and ADP5070ACPZ-R7, the MCP16411T-I/MN uniquely combines sub-1V startup, auto-bypass, and dual-mode PFM/PWM-making it optimal for maximizing runtime across the full discharge curve of consumer-grade primary and rechargeable cells.

FAQ
What is the minimum input voltage required for MCP16411T-I/MN to start up?
The MCP16411T-I/MN requires a minimum of 0.8 V after startup, but its actual startup voltage is higher-typically 1.0 V-due to internal bias requirements. This allows reliable operation from partially discharged single-cell alkaline or NiMH batteries, and makes the MCP16411T-I/MN suitable for applications where deep discharge tolerance is critical, such as long-life remote controls.
Does MCP16411T-I/MN support fixed or adjustable output voltage?
The MCP16411T-I/MN supports both configurations via the FB pin: a resistor divider sets adjustable output (e.g., 3.3 V or 5.0 V), while omitting the upper resistor yields fixed output determined by internal reference (0.6 V). This flexibility enables one PCB design to serve multiple voltage rails, reducing inventory complexity without sacrificing performance in the MCP16411T-I/MN implementation.
How does the auto-bypass feature improve battery life in MCP16411T-I/MN?
The auto-bypass feature in MCP16411T-I/MN engages when VIN ≥ VOUT − 100 mV, routing input directly to output without switching. This eliminates switching losses and gate drive current, raising efficiency to >96% in high-battery states-extending usable capacity by up to 15% compared to conventional boost converters, especially in single-cell Li-ion applications where VIN overlaps VOUT for much of the discharge curve.
Is output discharge (DIS pin) active during normal operation of MCP16411T-I/MN?
No-the DIS pin on the MCP16411T-I/MN is inactive during normal regulation. It only activates when EN is pulled low (shutdown mode), turning on an internal FET to discharge the VOUT capacitor. This ensures safe power-down in medical and consumer devices, preventing residual voltage that could interfere with MCU reset or violate safety standards-confirming the MCP16411T-I/MN's compliance-ready design.
What package options are offered for MCP16411T-I/MN, and are they pin-compatible?
The MCP16411T-I/MN is available in 10-lead MSOP (3.0 mm × 4.9 mm) and 10-lead 3 mm × 3 mm TDFN packages. Both share identical pinout and thermal pad configuration-enabling direct PCB footprint interchangeability. This dual-package strategy lets designers optimize for cost (MSOP) or density (TDFN) without redesigning layout, reinforcing the MCP16411T-I/MN's adaptability across product generations.
