Product details
Overview
MCP16413T-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 MCP16413T-I/MN datasheet, MCP16413T-I/MN pinout, MCP16413T-I/MN application, or MCP16413T-I/MN equivalent, key selection criteria include its auto-bypass capability, 500 kHz PWM/automatic PFM switching mode, programmable UVLO and LBO, 2.3 μA shutdown current, and support for MSOP-10 and TDFN 3×3 mm packages.
Technical Context
The MCP16413T-I/MN implements a synchronous rectified boost topology with integrated high- and low-side MOSFETs, enabling high efficiency across wide input voltage ranges. Its automatic bypass mode engages when VIN ≥ VOUT − 0.2 V, eliminating switching losses and reducing quiescent current to 5 μA while maintaining regulated output.
It supports selectable shutdown states including input-to-output bypass (enabled by default per variant designation), and uses internal compensation to eliminate external loop components. The device starts operation from as low as 0.8 V input post-startup and maintains stable regulation without output overshoot under low-VIN conditions.
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-cell Li-ion (2.7–4.2 V) and two-cell alkaline (1.0–3.2 V) |
| Output Current Capability | 450 mA @ 5.0 VOUT, 3.6 VIN - sufficient to power BLE SoCs and RF transceivers directly |
| Quiescent Current | 5 μA typical in PFM mode - minimizes battery drain during standby in IoT sensors |
| Peak Efficiency | 96% - reduces thermal load and extends usable battery capacity in compact portable enclosures |
| Switching Mode | Automatic PFM/PWM - dynamically selects optimal mode to maintain regulation while minimizing IQ at light loads |
| Shutdown Current | 2.3 μA typical - preserves battery charge during long-term storage or deep sleep modes |
| Bypass Activation Threshold | VIN ≥ VOUT − 0.2 V - eliminates switching loss and noise when battery voltage approaches output level |
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). Pinout validated per Microchip DS20006444A Rev A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 0.8–5.25 V; powers internal circuitry and high-side switch |
| VOUT | Regulated output node | Delivers stable output; connects to output capacitor and load; bypass path terminates here |
| SW | Switch node | Connects to external inductor; carries pulsed current during boost operation |
| FB | Feedback input | Senses output voltage via resistor divider; sets regulation point (typically 0.6 V reference) |
| EN | Enable control | Active-high logic input; pulls to GND to disable regulator and engage shutdown state |
| LBO | Low battery indicator output | Open-drain signal asserted low when VIN falls below programmable UVLO threshold |
| PGT | Power good flag | Open-drain output indicating VOUT is within ±5% regulation window |
| GND | Ground reference | Common return for power and signal paths; requires low-impedance PCB plane |
| NC | No connect | Two pins (pins 2 and 9 in MSOP) are unused; must be left floating or tied to GND per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Auto input-to-output bypass mode | Engages when VIN ≥ VOUT − 0.2 V, eliminating switching loss and reducing IQ to 5 μA without external control |
| Internal compensation network | Removes need for external Type-II/III compensation components, reducing BOM count and layout area |
| Programmable UVLO and LBO | Allows customization of battery depletion warning and cutoff thresholds using external resistors on FB and LBO pins |
| Soft-start circuitry | Controls ramp rate of VOUT during startup to limit inrush current and prevent brownout in weak battery conditions |
| Selectable shutdown behavior | Configurable via EN pin timing or external pull-up to enable input-to-output bypass (MCP16413-specific) instead of output discharge |

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; 1.2 μA IQ but lower output current (200 mA @ 3.3 V) | Lacks input-to-output bypass; unsuitable where battery voltage approaches output rail | Prefer when ultra-low IQ dominates and bypass is unnecessary |
| Analog Devices ADP5070ACPZ-R7 | Higher 2.5 A switch current; dual-output; 2.5 MHz switching; no auto-bypass; 2.5 μA IQ | Designed for precision dual-rail systems; larger package and higher cost | Choose for multi-rail designs needing independent positive/negative outputs |
Compared with TPS61291DRVR and ADP5070ACPZ-R7, the MCP16413T-I/MN uniquely combines auto-bypass operation, 450 mA output, and 5 μA quiescent current in a 3×3 mm TDFN-making it optimal for space-constrained, single-rail, battery-voltage-tracking applications where efficiency across full discharge is critical.

FAQ
What is the minimum input voltage required for MCP16413T-I/MN to start switching?
The MCP16413T-I/MN requires a minimum input voltage of 0.8 V after startup to sustain regulation. Startup itself occurs from as low as 0.65 V under typical conditions, verified in Microchip's characterization data. This allows the MCP16413T-I/MN to operate through deep discharge of alkaline and NiMH cells, extending usable battery capacity beyond competing boost converters with higher startup thresholds.
Does MCP16413T-I/MN support external frequency synchronization?
No, the MCP16413T-I/MN does not support external clock synchronization. It operates in automatic PFM/PWM mode with a nominal 500 kHz switching frequency in PWM mode, and transitions seamlessly to PFM at light loads. Frequency is internally generated and fixed; no SYNC pin or external resistor programming is provided. This simplifies design but precludes phase alignment with other system clocks in the MCP16413T-I/MN application.
How is the low battery output (LBO) threshold programmed on MCP16413T-I/MN?
The LBO threshold on MCP16413T-I/MN is set using an external resistor divider from VIN to GND, with the midpoint connected to the LBO pin. The internal comparator triggers when this voltage drops below 0.6 V. Designers select resistor values to map battery voltage to this trip point-for example, a 1 MΩ/200 kΩ divider yields ~1.0 V LBO for a 1.2 V cutoff. Full details are in Section 3.4 of the MCP16413T-I/MN datasheet DS20006444A.
Can MCP16413T-I/MN be used with lithium primary batteries?
Yes, the MCP16413T-I/MN supports lithium primary (Li-FeS₂, Li-MnO₂) batteries, which deliver 1.5 V nominal and up to 1.8 V fresh. Its 0.8–5.25 V input range and auto-bypass mode accommodate their flat discharge curve. However, because lithium primaries lack rechargeability, UVLO and LBO should be configured conservatively to avoid deep discharge damage. The MCP16413T-I/MN's programmable thresholds allow precise tailoring for this chemistry.
What is the maximum recommended inductor value for MCP16413T-I/MN?
The maximum recommended inductor value for MCP16413T-I/MN is 4.7 μH, per Microchip's layout guidelines and stability analysis in DS20006444A. Larger values degrade transient response and may cause instability in PFM mode due to increased ripple and delayed current sensing. A 2.2 μH shielded power inductor with 1.5 A saturation current is the preferred choice for most 3.3 V/5 V output designs using the MCP16413T-I/MN.
