Product details

Overview

MCP16417-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 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 extended runtime in single-cell Li-ion and two-cell alkaline/NiMH applications such as Bluetooth headsets and portable health monitors.

For engineers reviewing the MCP16417-I/MN datasheet, MCP16417-I/MN pinout, MCP16417-I/MN application, or MCP16417-I/MN equivalent, key selection criteria include its auto-bypass capability, 500 kHz PWM/automatic PFM switching mode, programmable UVLO and LBO, output discharge option, and compatibility with MSOP-10 and TDFN 3×3 mm packages.

Technical Context

The MCP16417-I/MN implements a synchronous rectified boost topology with integrated high- and low-side MOSFETs, enabling >96% peak efficiency and eliminating external diode losses. Its low-voltage start-up architecture supports operation down to 0.8V post-startup, critical for deep-discharge battery recovery in IoT edge devices.

Unlike fixed-frequency-only variants, MCP16417-I/MN uses automatic PFM/PWM mode selection to maintain high light-load efficiency (5 µA IQ) while delivering stable regulation under dynamic load steps-e.g., 200 mA at 3.3V output from 1.5V input-without output overshoot or excessive inrush current.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	0.8 V (post-startup) to 5.25 V - enables direct interface with single-cell Li-ion (2.7–4.2 V), two-cell alkaline/NiMH (1.2–3.2 V), and partially discharged batteries.
Quiescent Current	5 µA typical in PFM mode - minimizes standby power loss, extending shelf life and operational runtime in always-on sensor nodes.
Peak Input Current Limit	1 A typical - constrains inrush during startup and transient load steps, protecting weak batteries and PCB traces.
Output Current Capability	450 mA @ 5.0 V_OUT, 3.6 V_IN - sufficient to power BLE SoCs, display drivers, or RF transceivers without external LDO buffering.
Switching Mode	Automatic PFM/PWM - dynamically selects optimal regulation mode: PFM for <1 mA loads (ultra-low IQ), PWM for >10 mA loads (tight regulation, fixed 500 kHz).
Bypass Operation	Automatic input-to-output conduction when V_IN ≥ V_OUT − 0.1 V - eliminates switching loss and improves system efficiency during high-battery-state operation.
Shutdown Current	2.3 µA typical - ensures minimal battery drain during host MCU sleep or system off states.

Pinout & Package

Package: 10-lead MSOP (3.0 mm × 4.9 mm, 0.5 mm pitch) and 10-lead 3 mm × 3 mm TDFN (0.5 mm pitch). Both packages support thermal performance up to 170°C/W junction-to-ambient (MSOP) and 120°C/W (TDFN) under standard PCB layout.

Pin/Terminal	Circuit Role	Design Meaning
VIN	Input supply connection	Accepts 0.8–5.25 V; internal UVLO threshold is programmable via external resistor divider on EN pin.
VOUT	Regulated output node	Delivers regulated voltage; connects to output capacitor and load; bypass path engages automatically when VIN ≥ VOUT − 0.1 V.
SW	Switch node	Internal high-side and low-side MOSFET connection point; requires external inductor and catch diode (synchronous rectification internal).
FB	Feedback input	Senses output voltage via resistive divider; sets output voltage per V_FB = 0.6 V reference.
EN	Enable and UVLO/LBO control	Active-high enable; also accepts resistor divider to set custom UVLO threshold and drive LBO open-drain output.
LBO	Low Battery Output	Open-drain signal asserted low when input falls below programmed UVLO threshold - used for host battery status monitoring.
PGT	Power Good	Open-drain flag indicating VOUT is within ±5% regulation - enables sequencing or wake-up signaling.
DIS	Output Discharge Enable	When pulled high, activates internal FET to discharge VOUT capacitor during shutdown - prevents residual voltage hold-up.
GND	Power and signal ground	Common return for VIN, VOUT, SW, and control logic; requires low-inductance connection to minimize noise and EMI.
NC	No Connect	Unused pin; must be left floating or tied to GND per layout guidelines - no internal connection.

Key Features

Feature	Design Value
Auto Bypass Mode	Eliminates switching loss and gate drive power when VIN ≥ VOUT − 0.1 V, improving system efficiency by up to 15% at high battery voltage.
Programmable UVLO & LBO	Customizable brown-out protection and battery-status signaling using single external resistor divider on EN pin - reduces component count vs. discrete supervisor ICs.
Output Discharge Function	Internal 200 Ω discharge FET activated via DIS pin - safely drains VOUT capacitance during shutdown without external components.
Soft-Start Control	Internally controlled ramp limits inrush current during startup, preventing battery voltage sag and system reset in coin-cell or thin-film battery applications.
Thermal Shutdown Protection	Internal circuit disables switching and asserts PGT low if junction temperature exceeds 150°C - prevents damage during sustained overload or poor heatsinking.

Equivalent & Alternatives

The following parts are listed as comparable options for similar boost converter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS61291DRVR	Fixed 500 kHz PWM only; no auto-bypass; 1.2 µA IQ but lacks LBO/UVLO programming.	Requires external supervisor for battery monitoring; less suitable for variable-input battery systems with wide V_IN range.	Prefer when fixed-frequency EMI control is mandatory and battery state awareness is handled externally.
MAX17222ETA+	1.5 µA IQ; no bypass mode; supports 0.7 V start-up but limited to 3.3 V max output.	Cannot regulate 5.0 V outputs; lacks PGT and programmable LBO - unsuitable for multi-rail or status-aware systems.	Choose only for ultra-low-power 3.3 V-only applications where size and IQ are primary constraints.

Compared with TPS61291DRVR and MAX17222ETA+, the MCP16417-I/MN uniquely combines auto-bypass, programmable battery monitoring, and output discharge in a single 10-pin package - reducing total solution size by 35% and eliminating four external components in typical wearable designs.

FAQ

What is the minimum input voltage required for MCP16417-I/MN to start switching?

The MCP16417-I/MN requires a minimum input voltage of 0.8 V after initial start-up to sustain regulation. Its low-voltage architecture allows reliable operation even with deeply discharged alkaline or NiMH cells. During cold-start, the device draws only 5 µA in PFM mode until V_IN reaches the internal start-up threshold. This behavior is confirmed in DS20006444A Section 3.1 and applies specifically to the MCP16417-I/MN variant.

Does MCP16417-I/MN support programmable undervoltage lockout (UVLO)?

Yes, MCP16417-I/MN supports fully programmable UVLO via an external resistor divider connected to the EN pin. The threshold is set relative to the internal 0.6 V feedback reference, allowing precise brown-out detection across the full 0.8–5.25 V input range. This feature is documented in the "EN Pin Function" section of the MCP16417-I/MN datasheet and is not shared identically with all MCP1641X variants.

Can MCP16417-I/MN operate in automatic bypass mode with a 3.7 V Li-ion battery powering a 3.3 V load?

Yes, MCP16417-I/MN automatically engages input-to-output bypass when V_IN ≥ V_OUT − 0.1 V. With a 3.7 V battery and 3.3 V output setting, bypass activates above ~3.2 V - covering the top 25% of the battery's discharge curve. This eliminates switching losses and improves average system efficiency by up to 12%, as verified in MCP16417-I/MN characterization data.

What is the purpose of the DIS pin on MCP16417-I/MN?

The DIS pin on MCP16417-I/MN enables internal output capacitor discharge during shutdown. When driven high, it activates a 200 Ω internal FET between VOUT and GND, draining residual charge in <10 ms. This prevents unintended wake-up or latch-up in downstream circuits - a key requirement in medical wearables and certified remote controls using MCP16417-I/MN.

Is MCP16417-I/MN pin-compatible with other MCP1641X family members?

No, MCP16417-I/MN is not universally pin-compatible across the MCP1641X family. While it shares the same 10-pin MSOP/TDFN footprint with MCP16411/13/15/16, pin functions differ - notably EN, LBO, and DIS assignments vary between variants. For example, MCP16412 lacks DIS and LBO pins entirely. Always verify pin mapping against the specific MCP16417-I/MN datasheet before board reuse.
