Product details
Overview
MCP16413-I/MN from Microchip Technology is a synchronous boost DC-DC converter with automatic input-to-output bypass mode, 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 with 3.6 V input, features 5 μA quiescent current in PFM mode, 96% peak efficiency, and operates down to 0.8 V input after startup-enabling extended runtime in Bluetooth headsets and remote controllers.
For engineers reviewing the MCP16413-I/MN datasheet, MCP16413-I/MN pinout, MCP16413-I/MN application, or MCP16413-I/MN equivalent, key selection criteria include its auto-bypass capability, 500 kHz fixed-frequency PWM option (not applicable-MCP16413 supports auto PFM/PWM), UVLO/LBO programmability, and 2.3 μA shutdown current for ultra-low-power IoT endpoint design.
Technical Context
The MCP16413-I/MN implements an adaptive control architecture that automatically transitions between boost regulation and direct input-to-output bypass based on VIN vs. VOUT relationship-eliminating switching losses when VIN ≥ VOUT − VDROP. Its internal compensation, soft-start circuitry, and integrated 1 A peak current limit enable stable startup from low-voltage batteries without overshoot or excessive inrush.
It operates in automatic PFM/PWM mode with no external mode-select pin; frequency varies dynamically under light load (PFM) and locks to ~500 kHz under heavier loads. The device includes programmable undervoltage lockout (UVLO) and Low Battery Output (LBO) with dedicated pins, supporting system-level battery monitoring and graceful shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.8 V (post-startup) to 5.25 V - enables operation across full discharge curve of single Li-ion (2.7–4.2 V) or two alkaline cells (0.8–3.2 V) |
| Quiescent Current | 5 μA typical in PFM mode - minimizes standby drain, critical for multi-year battery life in remote controls |
| Shutdown Current | 2.3 μA typical - preserves battery charge during long idle periods in portable health monitors |
| Peak Efficiency | 96% - reduces thermal stress and extends usable capacity in compact enclosures like Bluetooth headsets |
| Output Current Capability | 450 mA @ 5.0 VOUT, 3.6 VIN - sufficient to power BLE SoCs and sensors in two-cell IoT nodes |
| Bypass Mode Activation | Automatic VIN-to-VOUT conduction when VIN ≥ VOUT − 0.15 V - eliminates switching loss and noise during high-battery-state operation |
| Switching Mode Control | Auto PFM/PWM - no external configuration needed; adapts dynamically to load for optimal light-load efficiency |
Pinout & Package
Package: 10-lead MSOP (3.0 mm × 4.9 mm, 0.5 mm pitch) with exposed thermal pad. Pin-compatible with TDFN variant but requires layout adjustment for thermal pad connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply rail | Accepts 0.8–5.25 V; connects directly to battery or power source; feeds internal LDO and bias circuits |
| GND | Power and signal reference | Common return for all internal circuits and external components; must be low-impedance connection to thermal pad |
| VOUT | Regulated output node | Delivers regulated voltage; connects to load and feedback divider; also serves as bypass path when enabled |
| FB | Feedback input | Senses output voltage via resistor divider; sets regulation point (typically 3.3 V or 5.0 V); high-impedance input |
| EN | Enable control | Active-high logic input; pulls device into shutdown (2.3 μA IQ) when low; internal pull-down |
| LBO | Low Battery Output | Open-drain output asserted low when VIN drops below programmed UVLO threshold; used for system battery warning |
| UVLO | Undervoltage Lockout adjust | Resistor-programmable threshold pin; sets turn-on/off hysteresis for battery brown-out protection |
| SW | Switch node | Connects to external inductor and catch diode (or internal FET in synchronous design); carries high di/dt switching current |
| PGT | Power Good indicator | Open-drain output signaling valid regulation (VOUT within ±5%); delays assertion until soft-start completes |
| DIS | Output discharge control | Not implemented on MCP16413-I/MN - this pin is reserved for bypass mode; connects internally to enable auto-bypass path |
Key Features
| Feature | Design Value |
|---|---|
| Auto Bypass Operation | Eliminates switching loss and EMI when VIN ≥ VOUT − 0.15 V, extending battery life and simplifying filtering in wearables |
| Integrated Soft Start | Controls output ramp rate to limit inrush current during cold start from depleted batteries (e.g., 0.8 V), preventing brownout |
| Programmable UVLO & LBO | Allows precise battery end-of-life detection using external resistors-enables predictable shutdown before system reset or data loss |
| 10-Lead MSOP Package | Enables compact PCB layout with thermal pad for >1 W dissipation; footprint compatible with TDFN variant for design reuse |
| Internal Compensation | Removes need for external compensation network-reduces BOM count by 2–3 passive components and accelerates design validation |

FAQ
What is the minimum input voltage required for MCP16413-I/MN to start up?
The MCP16413-I/MN requires a minimum of 0.8 V on VIN to initiate startup. This ultra-low start-up voltage allows reliable operation even with deeply discharged alkaline or NiMH cells. Once running, the device sustains regulation down to 0.8 V input, making it ideal for applications like remote controllers where battery voltage can fall below 1.0 V per cell. The MCP16413-I/MN achieves this through a low-voltage-designed architecture with optimized gate drive and internal biasing.
Does MCP16413-I/MN support fixed 5.0 V output without external resistors?
No, the MCP16413-I/MN does not support fixed-output variants. It requires an external resistor divider on the FB pin to set the output voltage-common configurations include 3.3 V (162 kΩ/100 kΩ) or 5.0 V (301 kΩ/100 kΩ). This flexibility allows designers to tailor VOUT precisely to their load requirements, unlike fixed-output alternatives. The MCP16413-I/MN's feedback architecture supports tight regulation (±2%) across temperature and load.
How does the auto-bypass function work in MCP16413-I/MN?
The MCP16413-I/MN automatically enables a low-resistance path from VIN to VOUT when input voltage exceeds output voltage minus ~0.15 V. During bypass, the internal switch remains off, eliminating switching losses, EMI, and gate drive current. This occurs seamlessly without external control-critical for maintaining efficiency in battery-powered devices like Bluetooth headsets during high-SOC operation. The MCP16413-I/MN exits bypass and resumes boost mode as battery voltage declines.
Can MCP16413-I/MN be used with single-cell Li-Po batteries?
Yes, the MCP16413-I/MN is explicitly qualified for single-cell Li-Ion/Li-Polymer batteries (2.7–4.2 V nominal). Its 0.8–5.25 V input range covers full discharge, and auto-bypass activates above ~3.15 V for a 3.3 V output, maximizing efficiency during peak battery voltage. The MCP16413-I/MN's low quiescent current and soft-start prevent overcurrent during Li-Po cold-start conditions, ensuring robust performance in wearable health monitors.
What is the purpose of the DIS pin on MCP16413-I/MN?
On the MCP16413-I/MN, the DIS pin is internally configured to enable auto-bypass mode-not output discharge. Unlike MCP16411/2/5/6 variants, this pin is not user-controllable; it connects to the internal bypass FET gate driver. Therefore, external connection to DIS is unnecessary and should remain unconnected or tied to GND per layout guidelines. This functional assignment distinguishes the MCP16413-I/MN within the MCP1641X family and aligns with its intended use in battery-optimized systems.
