Product details
Overview
MCP16413T-I/UN 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 or two-cell alkaline/NiMH portable devices like Bluetooth headsets and remote controllers.
For engineers reviewing the MCP16413T-I/UN datasheet, MCP16413T-I/UN pinout, MCP16413T-I/UN application, or MCP16413T-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.
Technical Context
The MCP16413T-I/UN implements a synchronous rectified boost topology with integrated high- and low-side MOSFETs, enabling >96% peak efficiency. Its adaptive control architecture automatically transitions between PFM and PWM modes based on load, maintaining regulation across 0.8V–5.25V input while suppressing inrush current via soft-start.
Unlike fixed-frequency variants (e.g., MCP16412), the MCP16413T-I/UN uses automatic PFM/PWM mode switching and supports input-to-output bypass during light-load or near-VOUT conditions-reducing conduction losses when VIN ≥ VOUT − 0.2V. Shutdown includes input-to-output bypass option and 2.3 µA typical leakage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.8V (post-startup) to 5.25V - enables direct operation from depleted single-cell Li-ion (2.7V–4.2V) or two-cell alkaline (1.0V–3.2V). |
| Quiescent Current | 5 µA typical in PFM mode - minimizes no-load battery drain in always-on IoT sensors. |
| Peak Efficiency | 96% - achieved at medium loads with synchronous rectification, reducing thermal stress in compact enclosures. |
| Output Current Capability | 450 mA @ 5.0VOUT, 3.6VIN - sufficient to power BLE SoCs and RF transceivers without external LDO post-regulation. |
| Shutdown Current | 2.3 µA typical - preserves battery charge during long standby periods in remote controls. |
| Bypass Mode Trigger | Automatic VIN-to-VOUT conduction when VIN ≥ VOUT − 0.2V - eliminates switching loss and improves system efficiency during battery "fresh" phase. |
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 surface-mount options suitable for space-constrained wearables and handhelds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 0.8V–5.25V; internal UVLO threshold programmable via external resistor divider. |
| VOUT | Regulated output node | Delivers stable output; connects directly to load or feedback network; bypass path originates here. |
| FB | Feedback input | Senses output voltage via resistive divider; sets regulated VOUT (e.g., 3.3V or 5.0V). |
| EN | Enable control input | Active-high logic input; pulls to GND for shutdown with 2.3 µA IQ; supports input-to-output bypass in shutdown state. |
| LBO | Low battery indicator output | Open-drain signal asserted low when VIN drops below programmable UVLO threshold - triggers host MCU alert. |
| PGT | Power good flag | Open-drain output indicating VOUT is within ±5% regulation - used for system power sequencing. |
| GND | Power and signal reference | Dual-function ground pin shared by analog and power sections; requires low-impedance PCB plane. |
| SW | Switch node | Internal high-side/low-side MOSFET connection point; requires careful layout to minimize EMI and ringing. |
Key Features
| Feature | Design Value |
|---|---|
| Auto Bypass Operation | Eliminates switching loss when VIN ≥ VOUT − 0.2V, extending usable battery capacity by up to 15% in single-cell Li-ion applications. |
| Soft-Start Control | Internally limits inrush current during startup - prevents brownout in weak batteries and avoids triggering host overcurrent protection. |
| Programmable UVLO & LBO | Customizable battery depletion warning and cutoff thresholds using external resistor networks - enables precise end-of-life detection per chemistry. |
| Selectable Shutdown Mode | Input-to-output bypass enabled in shutdown - maintains regulated rail for real-time clock or memory retention without external diode. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61099YFFR | Fixed 500 kHz PWM only; no auto-bypass; 1.2 µA shutdown current; 0.7V start-up. | Lacks input-to-output conduction path - less efficient at high battery voltage; better for cost-sensitive, non-battery-optimized designs. | Choose when lowest shutdown IQ is critical and bypass functionality is not required. |
| MAX17222ETA+ | PFM-only operation; 3 µA IQ; no programmable LBO/UVLO; 0.4V start-up; no bypass mode. | Optimized for ultra-low-voltage harvesting (e.g., energy harvesters); lacks battery monitoring features. | Prefer for sub-1V input sources where MCP16413T-I/UN's 0.8V minimum is insufficient. |
Compared with TPS61099YFFR and MAX17222ETA+, the MCP16413T-I/UN uniquely combines auto-bypass, programmable battery monitoring, and PFM/PWM adaptability-making it optimal for consumer battery-powered devices where runtime, voltage headroom, and system-level power management are co-optimized.

FAQ
What is the minimum input voltage required for MCP16413T-I/UN to start regulation?
The MCP16413T-I/UN achieves initial startup at 0.8V after start-up, with internal circuitry enabling reliable operation down to this threshold. This allows compatibility with deeply discharged single-cell Li-ion batteries and two-cell alkaline systems. The device maintains regulation across the full 0.8V–5.25V range, and its soft-start feature prevents output overshoot during low-VIN startup. Designers should verify minimum VIN under worst-case temperature and load conditions using the MCP16413T-I/UN datasheet graphs.
Does MCP16413T-I/UN support automatic transition between PFM and PWM modes?
Yes, the MCP16413T-I/UN implements automatic PFM/PWM mode switching based on load current-unlike fixed-frequency variants such as MCP16412. At light loads, it operates in PFM mode with 5 µA quiescent current; as load increases, it seamlessly transitions to PWM mode at 500 kHz to maintain tight output regulation. This dual-mode behavior is inherent to the MCP16413T-I/UN silicon and requires no external configuration.
How does the auto-bypass function work in MCP16413T-I/UN?
The MCP16413T-I/UN activates input-to-output bypass when VIN ≥ VOUT − 0.2V, routing power directly through an internal low-RDS(on) path instead of switching regulation. This eliminates switching losses and associated noise, improving efficiency by up to 15% during the "fresh battery" phase. Bypass is fully automatic and transparent to the user-no control pins or firmware intervention is needed for the MCP16413T-I/UN to engage or exit this mode.
Can MCP16413T-I/UN be used with single-cell Li-Po batteries?
Yes, the MCP16413T-I/UN is explicitly qualified for single-cell Li-Ion/Li-Polymer batteries (2.7V–4.2V), as confirmed in Microchip's official documentation. Its 0.8V–5.25V input range accommodates full discharge curves, and the programmable UVLO/LBO pins allow customization of low-battery thresholds per chemistry. The device's soft-start and low inrush current prevent stress on aging Li-Po cells, making MCP16413T-I/UN suitable for wearable and medical devices using this battery type.
What package options are available for MCP16413T-I/UN?
The MCP16413T-I/UN 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 heat dissipation and are compatible with standard reflow profiles. The TDFN variant provides superior thermal performance and smaller footprint-ideal for ultra-compact designs-while the MSOP offers easier prototyping and manual soldering. No other package variants are specified for the MCP16413T-I/UN.
