Product details
Overview
MCP16416-I/MN from Microchip Technology is a synchronous boost DC-DC converter with auto-bypass functionality, designed for single-cell Li-ion or two-cell alkaline/NiMH battery-powered systems. It delivers up to 450 mA output current at 5.0 V output from 3.6 V input, features 5 μA quiescent current in PFM mode, 500 kHz fixed-frequency PWM operation, and integrated UVLO with low-battery output signaling-enabling long runtime in Bluetooth headsets and portable health monitors.
For engineers reviewing the MCP16416-I/MN datasheet, MCP16416-I/MN pinout, MCP16416-I/MN application, or MCP16416-I/MN equivalent, key selection criteria include its automatic input-to-output bypass mode, 500 kHz switching frequency, 10-lead MSOP package, 0.8–5.25 V input range, and shutdown current of 2.3 μA-critical for ultra-low-power IoT endpoint design.
Technical Context
The MCP16416-I/MN implements a synchronous rectified boost topology with internal compensation and selectable fixed-frequency PWM control (500 kHz), eliminating external loop components. Its auto-bypass function engages when VIN ≥ VOUT − 0.2 V, routing input directly to output without switching to minimize conduction loss and extend battery life during high-VIN conditions.
This device integrates programmable undervoltage lockout (UVLO) and low-battery output (LBO) with hysteresis, supports output discharge during shutdown (enabled), and operates down to 0.8 V post-startup-enabling reliable startup from deeply discharged alkaline cells or aging Li-ion batteries.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.8 V (post-startup) to 5.25 V: supports full discharge curve of single-cell Li-ion and two-cell alkaline/NiMH. |
| Output Current Capability | 450 mA @ 5.0 VOUT, 3.6 VIN: sufficient for BLE SoCs and sensor hubs requiring regulated 5 V rail. |
| Quiescent Current | 5 μA typical in PFM mode: enables >1-year shelf life in remote controllers with coin-cell backup. |
| Switching Frequency | 500 kHz fixed PWM: allows compact 1.0–2.2 μH inductors and reduces EMI filtering burden. |
| Bypass Threshold | Auto-engages when VIN ≥ VOUT − 0.2 V: eliminates switching loss and improves efficiency above ~4.8 V input at 5 V output. |
| Shutdown Current | 2.3 μA typical: preserves battery charge during extended sleep modes in wearable devices. |
Pinout & Package
Package: 10-lead MSOP (3.0 mm × 4.9 mm, 0.5 mm pitch), RoHS-compliant, moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 0.8–5.25 V; connects to battery or power source; decoupling capacitor required. |
| GND | Power and signal reference | Common return path for input, output, and control circuitry; must be low-impedance plane. |
| VOUT | Regulated output node | Delivers boosted voltage; connects to load and output capacitor; bypass mode routes VIN directly here. |
| SW | Switch node | Connects to inductor and internal high/low-side MOSFETs; requires tight layout to minimize ringing. |
| FB | Feedback input | Senses output voltage via resistor divider; sets regulation point (e.g., 5.0 V with 301 kΩ/100 kΩ). |
| EN | Enable control input | Active-high logic input; pulls low to enter shutdown (2.3 μA IQ); internal pull-down. |
| LBO | Low-battery open-drain output | Asserts low when VIN drops below UVLO threshold; drives MCU GPIO or LED indicator. |
| PGT | Power-good open-drain output | Signals valid regulation (VOUT within ±5%); used for system power sequencing or fault detection. |
| DIS | Output discharge enable | When high, activates internal FET to discharge VOUT capacitor during shutdown-prevents residual voltage hold-up. |
| NC | No connect | Pin 10 is unconnected; must remain floating or grounded per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated auto-bypass mode | Eliminates switching loss when VIN approaches VOUT, improving efficiency by up to 15% at high battery SOC in portable instruments. |
| Programmable UVLO + LBO | Allows customization of battery depletion warning and cutoff thresholds (e.g., 2.8 V UVLO with 100 mV hysteresis) for optimal cell utilization. |
| Output discharge (DIS pin) | Prevents unintended wake-up or latch-up in microcontroller-based systems by actively draining VOUT capacitance during shutdown. |
| Internal compensation | Removes need for external Type-II/III compensation network, reducing BOM count by 3–4 passive components and PCB area by ≥12 mm². |

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 | Lower IQ (800 nA shutdown), but no auto-bypass; fixed 1.2 MHz switching; max 300 mA @ 5 V. | Preferred for coin-cell applications demanding extreme ultra-low-IQ, but unsuitable where VIN approaches VOUT frequently. | Select TPS61291DRVR only if battery voltage stays well below output (e.g., 1.5 V → 5 V), and bypass functionality is unnecessary. |
| Analog Devices ADP5070ACPZ-R7 | Higher output current (500 mA), dual-output, but 2.5 μA quiescent current only in skip mode; no LBO/PGT pins. | Used in dual-rail systems (e.g., ±3.3 V), but lacks integrated battery monitoring signals needed for portable health devices. | Choose ADP5070ACPZ-R7 when dual outputs or higher current are mandatory, and external UVLO/LBO supervision can be added. |
Compared with TPS61291DRVR and ADP5070ACPZ-R7, the MCP16416-I/MN uniquely combines auto-bypass, integrated LBO/PGT, and 500 kHz PWM in a 10-pin MSOP-making it optimal for single-rail, battery-voltage-tracking applications where efficiency across full SOC is critical.

FAQ
What is the minimum input voltage required for MCP16416-I/MN to start switching?
The MCP16416-I/MN starts switching at an input voltage of 0.8 V after initial startup. This low startup threshold enables operation from nearly depleted alkaline or NiMH cells, supporting full utilization of two-cell battery packs down to ~0.9 V per cell. The device maintains regulation through the entire discharge curve, and the 0.8 V specification is verified under typical temperature and load conditions per DS20006444A.
Does MCP16416-I/MN support automatic transition between PWM and PFM modes?
No, the MCP16416-I/MN operates exclusively in fixed-frequency PWM mode at 500 kHz. Unlike MCP16411/3/5/7 variants, it does not implement automatic PFM/PWM mode switching. This ensures predictable EMI profile and consistent transient response-key for timing-sensitive loads like BLE radios and audio codecs in designs using MCP16416-I/MN.
Can the LBO pin of MCP16416-I/MN be used to trigger a controlled system shutdown?
Yes, the LBO pin on MCP16416-I/MN is an open-drain output that asserts low when input voltage falls below the programmed UVLO threshold. It can directly interface with a microcontroller's interrupt-capable GPIO to initiate graceful firmware shutdown, data save, or display blanking before battery exhaustion-enabling reliable end-of-life behavior in portable health devices using MCP16416-I/MN.
What is the purpose of the DIS pin on MCP16416-I/MN, and how is it configured?
The DIS (discharge) pin on MCP16416-I/MN enables active discharge of the output capacitor during shutdown. When driven high, it turns on an internal FET between VOUT and GND, safely bleeding stored charge. This prevents residual voltage from interfering with MCU reset sequencing or causing false wake-ups-critical in remote controllers and wearables using MCP16416-I/MN.
Is the MCP16416-I/MN pin-compatible with other members of the MCP1641X family?
No, the MCP16416-I/MN is not fully pin-compatible with all MCP1641X variants. While it shares the same 10-lead MSOP package and core pin assignments (VIN, GND, VOUT, SW, FB, EN, LBO, PGT, DIS, NC), functions like UVLO programming and shutdown behavior differ across variants. For example, MCP16413/4/7/8 support input-to-output bypass instead of output discharge-requiring schematic and firmware validation before substitution.
