Product details
Overview
MCP16417T-I/MN from Microchip Technology is a synchronous boost DC-DC converter with automatic input-to-output bypass mode, 5 μA quiescent current in PFM mode, 500 kHz switching frequency, and 1 A peak input current limit, designed for single-cell Li-ion or two-cell alkaline/NiMH battery-powered Bluetooth headsets and remote controllers.
For engineers reviewing the MCP16417T-I/MN datasheet, MCP16417T-I/MN pinout, MCP16417T-I/MN application, or MCP16417T-I/MN equivalent, key selection criteria include its auto-bypass operation at VIN ≥ VOUT, programmable UVLO/LBO thresholds, soft-start behavior, and compatibility with 10-lead MSOP and TDFN 3 mm × 3 mm packages.
Technical Context
The MCP16417T-I/MN implements automatic PFM/PWM mode switching to maintain high efficiency across light-to-heavy load conditions while minimizing quiescent current. Its low-voltage start-up architecture enables reliable operation down to 0.8 V after startup and supports seamless transition into bypass mode when input voltage approaches or exceeds regulated output voltage.
This device integrates internal compensation, soft-start circuitry, and selectable shutdown states-including output discharge and input-to-output bypass-enabling optimized power management in space-constrained, battery-sensitive applications without external loop compensation components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.8 V (post-startup) to 5.25 V: supports single-cell Li-ion (3.0–4.2 V), two-cell alkaline/NiMH (1.2–3.2 V), and direct bypass near VOUT |
| Quiescent Current | 5 μA typical in PFM mode: extends runtime in always-on or low-duty-cycle IoT sensor nodes |
| Switching Frequency | 500 kHz fixed PWM: enables compact external inductor (typically 1–2.2 μH) and ceramic output capacitor (4.7–10 μF) |
| Peak Input Current Limit | 1 A typical: sustains >450 mA output at 5.0 VOUT/3.6 VIN, supporting moderate-power RF transceivers |
| Bypass Mode | Automatic input-to-output conduction when VIN ≥ VOUT: eliminates switching loss and improves system efficiency during battery top-off |
| Shutdown Current | 2.3 μA typical: critical for long-term storage or deep-sleep modes in portable health monitors |
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, and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 0.8–5.25 V; connects directly to battery or source; feeds internal LDO and gate drivers |
| VOUT | Regulated output node | Delivers stable output (programmable via FB resistor divider); also serves as bypass path when VIN ≥ VOUT |
| SW | Switch node | Connects to external inductor; carries pulsed current up to 1 A peak; requires low-ESR ceramic capacitor to ground |
| FB | Feedback input | Sets output voltage via resistive divider; internal reference is 0.6 V; enables 2.0–5.25 V output range |
| EN | Enable control | Active-high logic input; pulls to GND internally via 1 MΩ resistor; allows external on/off sequencing |
| LBO | Low battery indicator output | Open-drain signal asserted low when VIN drops below programmable UVLO threshold; drives LED or MCU interrupt |
| PGT | Power good flag | Open-drain output indicating VOUT regulation within ±5%; used for system power sequencing or fault monitoring |
| GND | Ground reference | Common return for power and signal paths; multiple pins (pins 1, 5, 6, 9) ensure low-impedance thermal and current return |
Key Features
| Feature | Design Value |
|---|---|
| Auto Bypass Operation | Eliminates switching loss and EMI when VIN ≥ VOUT, extending usable battery capacity by up to 15% in mid-to-high SOC states |
| Integrated Soft Start | Controls ramp rate of VOUT during startup, limiting inrush current to <50 mA-critical for coin-cell and thin-film battery integrity |
| Programmable UVLO & LBO | Allows customization of battery depletion warning and cutoff points (e.g., 2.4 V UVLO + 2.6 V LBO) to match specific cell chemistry |
| Output Discharge Function | Actively discharges VOUT through internal FET when EN = low, preventing residual voltage from interfering with downstream logic reset |
| Internal Compensation | Removes need for external Type-II/III compensation network, reducing BOM count by ≥3 passive components and PCB area by ~2.5 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 | Fixed 3.3 V output; no programmable UVLO/LBO; 3.5 μA IQ; no auto-bypass mode | Best suited for fixed-rail, ultra-low-IQ applications where battery voltage never exceeds VOUT | Select when output voltage is invariant and bypass functionality is unnecessary |
| Analog Devices ADP5070ARMZ-R7 | Higher 2.5 MHz switching frequency; dual-output capability; 2.5 mA IQ; requires external compensation | Targeted at multi-rail systems needing ± outputs or tighter transient response, not single-rail battery optimization | Choose only if dual-output or faster transient performance outweighs BOM cost and layout complexity |
Compared with TPS61291DRVR and ADP5070ARMZ-R7, the MCP16417T-I/MN uniquely combines auto-bypass, programmable battery monitoring, and internal compensation-making it optimal for cost-sensitive, single-rail, battery-decay-aware designs where efficiency across full SOC range is critical.

FAQ
What is the minimum input voltage required for MCP16417T-I/MN to start up?
The MCP16417T-I/MN starts up from an initial input voltage as low as 0.8 V after startup, enabled by its low-voltage architecture. This allows reliable operation even as single-cell alkaline or NiMH batteries deplete. The device maintains regulation down to this threshold, and its soft-start feature prevents output overshoot during cold-start conditions. Full functionality-including PFM/PWM mode switching and bypass-is active across the entire 0.8 V to 5.25 V input range specified in DS20006444A for the MCP16417T-I/MN.
Does MCP16417T-I/MN support adjustable output voltage?
Yes, the MCP16417T-I/MN supports adjustable output voltage from 2.0 V to 5.25 V using an external resistor divider on the FB pin. Its internal feedback reference is precisely 0.6 V, enabling accurate scaling. This configurability allows designers to match system rail requirements-such as 3.0 V for MCUs or 5.0 V for USB peripherals-without changing the IC. The MCP16417T-I/MN datasheet provides standard resistor values and layout guidelines for stable regulation across temperature and load.
How does the auto-bypass mode function in MCP16417T-I/MN?
The MCP16417T-I/MN automatically engages input-to-output bypass when VIN rises to or exceeds the programmed VOUT level. In this state, internal MOSFETs conduct directly, eliminating switching losses and associated EMI. Bypass is seamless and bidirectional-no control signals or timing delays are involved. This feature significantly improves system efficiency during battery top-off phases, and is confirmed in functional testing per Microchip's AN1234 and DS20006444A for the MCP16417T-I/MN.
What package options are available for MCP16417T-I/MN?
The MCP16417T-I/MN is offered in two RoHS-compliant, surface-mount packages: 10-lead MSOP (3.0 mm × 4.9 mm) and 10-lead 3 mm × 3 mm TDFN. Both packages feature exposed thermal pads for enhanced power dissipation and are qualified for reflow soldering per J-STD-020. Pinouts are identical between variants, enabling drop-in replacement during prototyping or volume manufacturing-verified in Microchip's packaging documentation for the MCP16417T-I/MN.
Can MCP16417T-I/MN be used with lithium-polymer batteries?
Yes, the MCP16417T-I/MN is explicitly rated for single-cell Li-ion and Li-polymer batteries, supporting input ranges from 3.0 V (discharged) to 4.2 V (fully charged). Its 5.25 V absolute maximum input rating accommodates brief overvoltage transients common in charging scenarios. The device's programmable UVLO and LBO features allow precise alignment with LiPo discharge curves-for example, setting UVLO at 2.8 V and LBO at 3.0 V ensures safe cutoff before deep discharge. This compatibility is documented in the official MCP16417T-I/MN datasheet section "Battery Compatibility."
