Product details
Overview
MCP16413-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 output at 5.0V with 3.6V input, achieves 96% peak efficiency, and features 5 µA quiescent current in PFM mode-enabling extended runtime in single-cell Li-ion or two-cell alkaline/NiMH systems.
For engineers reviewing the MCP16413-I/UN datasheet, MCP16413-I/UN pinout, MCP16413-I/UN application, or MCP16413-I/UN equivalent, key selection criteria include its auto-bypass capability, 2.3 µA shutdown current, selectable PFM/PWM operation, programmable UVLO/LBO, and support for MSOP-10 and TDFN 3×3 mm packages in industrial temperature range (–40°C to +85°C).
Technical Context
The MCP16413-I/UN implements a synchronous rectified boost topology with integrated high- and low-side MOSFETs, enabling high efficiency across wide load and input voltage ranges. Its auto-bypass function engages when VIN ≥ VOUT – 100 mV, eliminating switching losses and reducing quiescent current to 2.3 µA in shutdown.
It supports automatic PFM/PWM mode transition to maintain regulation under light loads while delivering stable output during transient demand. The device includes internal compensation, soft-start circuitry limiting inrush current, and programmable undervoltage lockout with low-battery output flag-critical for battery state monitoring in wearables and remote controls.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.8 V (post-startup) to 5.25 V - supports direct operation from depleted single-cell Li-ion (2.7 V) or fresh two-cell alkaline (3.2 V) |
| Output Current Capability | 450 mA @ 5.0 VOUT, 3.6 VIN - sufficient to power Bluetooth radios and sensor subsystems without external pass devices |
| Quiescent Current | 5 µA typical in PFM mode - minimizes standby drain on coin-cell or small Li-ion batteries |
| Shutdown Current | 2.3 µA typical - enables ultra-low-power system sleep states in IoT endpoints |
| Switching Mode | Automatic PFM/PWM - maintains regulation down to µA loads while avoiding audible noise at light loads |
| Bypass Activation Threshold | VIN ≥ VOUT – 100 mV - eliminates switching loss when input voltage approaches or exceeds regulated output |
| Operating Temperature | –40°C to +85°C - qualified for industrial and consumer portable equipment environments |
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 RoHS-compliant and rated for industrial temperature range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 0.8–5.25 V; internally powers bias circuitry and gate drivers |
| VOUT | Regulated output node | Connects to output capacitor and load; bypass path routes directly from VIN when enabled |
| FB | Feedback input | Senses output via resistor divider; sets regulated voltage (e.g., 3.3 V or 5.0 V) |
| EN | Enable control input | Active-high logic input; pulls to GND for shutdown (2.3 µA IQ) |
| LBO | Low-battery open-drain output | Asserts low when VIN drops below programmable UVLO threshold - signals host MCU for battery management |
| PGT | Power-good indicator | Open-drain output asserting high when VOUT is within ±5% regulation - used for system sequencing |
| GND | Power and signal reference | Dual-function ground plane; requires low-impedance layout for EMI and efficiency |
| SW | Switch node | Connects internal high- and low-side MOSFETs; requires careful routing and ceramic output capacitor placement |
Key Features
| Feature | Design Value |
|---|---|
| Auto input-to-output bypass | Engages when VIN ≥ VOUT – 100 mV, eliminating switching loss and reducing system IQ to 2.3 µA in hold-up mode |
| Integrated soft-start | Controls ramp rate of VOUT at startup to limit inrush current - prevents brownout in weak battery conditions |
| Programmable UVLO & LBO | Configurable via external resistor divider on FB pin - enables precise battery depletion detection without external comparators |
| Internal compensation | Eliminates need for external compensation network - reduces BOM count and PCB area in space-constrained wearables |
| Output discharge option | Not implemented on MCP16413-I/UN; instead supports input-to-output bypass during shutdown - preserves battery energy |

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 500 kHz PWM only; no auto-bypass; 3.5 µA IQ in shutdown; requires external compensation | Lacks input-to-output bypass - less efficient near end-of-life battery voltage | Prefer when fixed frequency and minimal external components outweigh bypass benefit |
| Analog Devices ADP5070ACPZ-R7 | Higher 2.5 MHz switching frequency; dual-output; 2.5 µA shutdown IQ; no auto-bypass; requires external loop compensation | Designed for compact dual-rail systems - not optimized for single-output battery utilization | Choose when generating both positive and negative rails from one cell is required |
Compared with TPS61291DRVR and ADP5070ACPZ-R7, the MCP16413-I/UN uniquely combines auto-bypass, 5 µA PFM IQ, and internal compensation - delivering superior battery runtime in single-rail, variable-input portable systems without increasing design complexity.

FAQ
What is the minimum input voltage required for MCP16413-I/UN to start regulation?
The MCP16413-I/UN starts regulation at 0.8 V after initial startup. It uses a low-voltage architecture that enables reliable startup even from deeply discharged single-cell Li-ion batteries (down to ~2.5 V) or two-cell alkaline (down to ~1.6 V total), thanks to internal charge pump and optimized gate drive. This ensures consistent operation in MCP16413-I/UN-based designs across full battery discharge profiles.
Does MCP16413-I/UN support adjustable output voltage?
Yes, MCP16413-I/UN supports adjustable output voltage via an external resistor divider on the FB pin. The feedback threshold is 0.6 V, allowing outputs from 2.5 V to 5.25 V using standard resistor ratios. This flexibility enables MCP16413-I/UN to power diverse loads - including 3.3 V MCUs, 5.0 V sensors, or 2.8 V RF modules - without changing the IC.
How does the auto-bypass feature improve battery life in MCP16413-I/UN applications?
The auto-bypass feature in MCP16413-I/UN engages when VIN ≥ VOUT – 100 mV, disabling switching and routing input directly to output. This reduces quiescent current to 2.3 µA and eliminates switching losses - extending usable battery capacity by up to 22% in applications like remote controls where VIN spends significant time near VOUT. MCP16413-I/UN thus maximizes energy extraction from primary and rechargeable cells.
What package options are offered for MCP16413-I/UN?
MCP16413-I/UN is available in two surface-mount packages: 10-lead MSOP (3.0 mm × 4.9 mm, 0.5 mm pitch) and 10-lead 3 mm × 3 mm TDFN. Both are lead-free, RoHS-compliant, and qualified for industrial temperature range (–40°C to +85°C). The TDFN variant offers lower thermal resistance and smaller footprint - ideal for ultra-compact MCP16413-I/UN implementations in wearables and hearing aids.
Is MCP16413-I/UN pin-compatible with other MCP1641X family members?
No, MCP16413-I/UN is not fully pin-compatible with all MCP1641X variants. While it shares the same 10-pin MSOP/TDFN footprint and core pin functions (VIN, VOUT, FB, EN, etc.), pin assignments for LBO, PGT, and SW differ across subtypes (e.g., MCP16411 vs. MCP16413). Always verify pinout against DS20006444A Rev A for MCP16413-I/UN - substituting other MCP1641X devices without layout review may cause functional failure.
