Product details
Overview
MCP16414-I/UN 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, and supports 500 kHz PWM switching. Used in Bluetooth headsets and remote controllers where battery life and low-voltage startup are critical.
For engineers reviewing the MCP16414-I/UN datasheet, MCP16414-I/UN pinout, MCP16414-I/UN application, or MCP16414-I/UN equivalent, key selection criteria include its auto-bypass capability, 500 kHz fixed-frequency PWM operation, 10-lead MSOP package, UVLO/LBO programmability, and compatibility with single-cell Li-ion or two-cell alkaline/NiMH sources.
Technical Context
The MCP16414-I/UN implements a synchronous rectified boost topology with integrated power switches and internal compensation, eliminating external loop compensation components. Its architecture enables seamless transition between active boost and direct input-to-output bypass when VIN ≥ VOUT – reducing conduction loss and extending runtime in partial-discharge battery states.
It operates exclusively in fixed-frequency PWM mode (500 kHz), distinguishing it from PFM/PWM hybrid variants in the MCP1641X family. Shutdown current is 2.3 μA typical, and it supports programmable undervoltage lockout and low-battery output signaling via dedicated pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.8V (post-startup) to 5.25V - supports full discharge of single-cell Li-ion (2.7–4.2V) and two-cell alkaline/NiMH (1.2–3.2V). |
| Output Current Capability | 450 mA @ 5.0VOUT, 3.6VIN - sufficient for BLE SoCs and sensor hubs requiring regulated 5V rail. |
| Quiescent Current | 5 μA typical in PFM mode - minimizes standby drain on coin-cell or small Li-ion batteries. |
| Switching Frequency | 500 kHz fixed PWM - enables compact external inductor (e.g., 1–2.2 μH) and reduces EMI filtering burden. |
| Bypass Mode | Automatic VIN-to-VOUT connection when VIN ≥ VOUT - eliminates switching loss and improves efficiency above ~3.6V input for 5V output. |
| Shutdown Current | 2.3 μA typical - ensures negligible battery drain during system sleep or off-state. |
| UVLO & LBO | Programmable via external resistors - allows precise battery voltage monitoring and graceful system shutdown before deep discharge. |
Pinout & Package
Package: 10-lead MSOP (3.0 mm × 4.9 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 0.8–5.25V; powers internal circuitry and high-side switch; connects directly to battery or source. |
| GND | Power and signal reference | Common return path for input, output, and control circuits; must be low-impedance plane. |
| VOUT | Regulated output node | Delivers boosted or bypassed output; requires local ceramic capacitor (≥10 μF) for stability. |
| SW | Switch node | Connects to external inductor and catch diode (internal sync FET); carries high di/dt switching current. |
| FB | Feedback input | Senses output voltage via resistor divider; sets regulation point (e.g., 5.0V with 162k/100k divider). |
| EN | Enable control | Active-high logic input; pulls to GND to disable regulator and enter 2.3 μA shutdown state. |
| UVLO | Undervoltage lockout adjust | Resistor-programmable threshold; disables regulator if VIN drops below set point to prevent brownout. |
| LBO | Low battery output | Open-drain flag asserted when VIN falls below programmed threshold; signals host MCU for battery management. |
| DIS | Output discharge enable | When high, activates internal FET to discharge VOUT capacitor during shutdown - prevents residual voltage hold-up. |
| NC | No connect | Internally unused; must be left floating or tied to GND per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Auto Bypass Mode | Eliminates switching loss when VIN ≥ VOUT, improving efficiency by up to 15% at mid-to-high battery voltage without external control logic. |
| Fixed 500 kHz PWM | Enables predictable EMI profile and consistent inductor sizing across designs; avoids frequency jitter of PFM modes. |
| Programmable UVLO/LBO | Allows customization of battery cutoff and warning thresholds using two external resistors - supports diverse chemistries and system requirements. |
| Integrated Output Discharge | Prevents unsafe residual voltage on VOUT after shutdown - critical for USB-OTG or dual-power-rail systems requiring fast power-domain isolation. |
| Internal Compensation | Removes need for external compensation network, reducing BOM count by ≥3 components and simplifying layout validation. |
Applications
| Wireless Audio Accessories | Portable Medical Sensors |
|---|---|

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 TPS610992DRVR | Lower IQ (300 nA), but no auto-bypass; fixed 1.2 MHz switching; max output 5.5V. | Lacks VIN-to-VOUT bypass - less efficient above 3.3V input for 5V output; better suited for ultra-low-IQ always-on sensors. | Select TPS610992DRVR only if sub-μA quiescent current dominates over mid-voltage efficiency. |
| Analog Devices ADP5070ACPZ-R7 | Higher output current (500 mA), but larger 16-lead LFCSP; no auto-bypass; requires external compensation. | Supports higher load currents and dual outputs, but increases BOM cost and layout complexity; no battery-savvy bypass behavior. | Choose ADP5070ACPZ-R7 when >450 mA sustained output or dual-rail generation is required, not for battery optimization. |
Compared with TPS610992DRVR and ADP5070ACPZ-R7, the MCP16414-I/UN uniquely balances ultra-low IQ, fixed-frequency predictability, and auto-bypass efficiency - making it optimal for single-rail, battery-constrained IoT endpoints where runtime and simplicity are co-priorities.

FAQ
What is the minimum input voltage required for MCP16414-I/UN to start up?
The MCP16414-I/UN requires a minimum of 0.8V after startup to maintain regulation, but its actual startup voltage is higher - typically 0.95V under light load with recommended external components. This enables reliable operation from deeply discharged NiMH or alkaline cells. The MCP16414-I/UN integrates a low-voltage-startup architecture to avoid output overshoot during cold-start conditions.
Does MCP16414-I/UN support automatic transition between boost and bypass modes?
Yes, the MCP16414-I/UN automatically engages input-to-output bypass when VIN ≥ VOUT, eliminating switching losses without external control. This behavior is inherent to the device's internal comparator and pass-FET structure. The MCP16414-I/UN does not require firmware intervention or external logic to activate bypass - it occurs seamlessly during normal operation as battery voltage declines.
What is the purpose of the DIS pin on MCP16414-I/UN?
When driven high, the DIS pin on MCP16414-I/UN activates an internal discharge FET that safely bleeds charge from the VOUT capacitor during shutdown. This prevents residual voltage from interfering with downstream logic or violating USB-OTG power sequencing requirements. The MCP16414-I/UN's DIS function is hardware-controlled and independent of EN pin state.
Can MCP16414-I/UN be used with a single-cell Li-ion battery?
Yes, the MCP16414-I/UN is explicitly rated for single-cell Li-ion (2.7–4.2V) and Li-Polymer sources. Its 0.8–5.25V input range and auto-bypass mode allow it to deliver regulated 5.0V output efficiently across the full battery discharge curve - boosting when VIN < 5.0V and bypassing when VIN ≥ 5.0V. The MCP16414-I/UN's low 5 μA quiescent current further preserves capacity during idle periods.
How does the UVLO pin on MCP16414-I/UN differ from the LBO pin?
The UVLO pin on MCP16414-I/UN sets the input voltage threshold below which the regulator disables entirely to prevent unstable operation; the LBO pin is an open-drain output that asserts a logic-low signal when VIN falls below a separately programmable threshold. Both use external resistor dividers, but UVLO controls enablement while LBO provides a status flag - allowing the MCP16414-I/UN to support both hard shutdown and early-warning battery management in one device.
