Product details
Overview
MP3414AGJ-P from Monolithic Power Systems is a synchronous step-up DC-DC converter IC with true output disconnect, supporting 1.8V–5.5V input and up to 5.5V/3A peak output. It integrates P-channel and N-channel MOSFETs (RDS(ON) = 80 mΩ / 70 mΩ), operates at fixed 1 MHz, delivers 97% efficiency, and draws only 22 µA quiescent current - ideal for battery-powered portable media players and wireless peripherals.
For engineers reviewing the MP3414AGJ-P datasheet, MP3414AGJ-P pinout, MP3414AGJ-P application, or MP3414AGJ-P equivalent, key selection criteria include its 1.8V startup capability, <1 µA shutdown current, internal soft start and compensation, inrush current limiting, and OVP/SCP/OTP protection - all in an 8-pin TSOT23 package.
Technical Context
The MP3414AGJ-P uses fixed-frequency current-mode PWM control with internal slope compensation and lossless NMOS current sensing. Its dual-phase operation includes linear charge mode (PMOS-controlled) at startup and boost switching mode (NMOS/PMOS synchronous rectification) once VOUT ≥ VIN, enabling seamless transition and precise peak-current limiting at 3.6 A.
It implements true output disconnect via controlled PMOS gate drive that eliminates body diode conduction, allowing full VOUT discharge to 0 V and sub-1 µA shutdown supply current. Protection features include thermal shutdown (155°C trip, 130°C hysteresis), over-voltage (6 V threshold), and short-circuit recovery with automatic restart.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8 V to 5.5 V - enables direct operation from single-cell Li-ion (2.8–4.2 V) or two/three alkaline/NiMH cells (1.8–4.5 V). |
| Output Voltage | Up to 5.5 V - programmable via external resistor divider; supports standard 5 V USB-peripheral rail generation. |
| Switching Frequency | 1 MHz (±20%) - permits use of compact 1–2.2 µH inductors and low-ESR ceramic capacitors for space-constrained designs. |
| Quiescent Current | 22 µA at 3.3 VIN/5 VOUT - minimizes battery drain in always-on or low-duty-cycle portable systems. |
| Shutdown Current | <1 µA - ensures near-zero standby power when EN is pulled low, critical for long shelf-life medical devices. |
| Peak Switch Current | 3.6 A - supports sustained 1 A output at 5 V from 2.8 V input with margin for transient loads. |
| Efficiency | Up to 97% - achieved via integrated synchronous rectification and low RDS(ON) MOSFETs, reducing heat and extending battery runtime. |
| Protection Features | OVP (6 V), SCP, OTP (155°C), and inrush limiting - eliminates need for external fault-handling circuitry in end equipment. |
Pinout & Package
MP3414AGJ-P is housed in a thermally enhanced 8-pin TSOT23 package (2.9 mm × 1.6 mm × 0.85 mm), optimized for high-power density and PCB area efficiency in portable applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Power input supply | Bias source during startup; must be locally bypassed with ≥10 µF ceramic capacitor to suppress ripple and support inrush limiting. |
| 2 OUT | Regulated output node | Drain of internal PMOS rectifier; connects directly to output filter; true disconnect isolates load from input when EN = low. |
| 3 SW | Switch node | Connection point between internal NMOS and PMOS; requires shortest possible trace to inductor to minimize EMI and voltage spikes. |
| 4 PGND | Power ground return | High-current return path for inductor and MOSFETs; must be tied to large copper pour and vias for thermal relief. |
| 5 FTY | Factory test pin | No user connection required; leave floating or tie to GND per layout guidelines - no functional impact in normal operation. |
| 6 AGND | Analog ground reference | Reference for FB and error amplifier; must be separated from PGND and connected at single point to avoid noise coupling. |
| 7 FB | Feedback input | Senses output voltage via resistive divider; internal 600 mV reference enables precise VOUT programming (e.g., 5 V with 1 MΩ/137 kΩ). |
| 8 EN | Enable control input | Logic-level interface: >1.2 V enables regulation; <0.4 V forces full shutdown with output disconnect and sub-1 µA IQ. |
Key Features
| Feature | Design Value |
|---|---|
| True output disconnect | PMOS gate control fully isolates OUT from IN during shutdown, enabling zero-load leakage and safe hot-swap capability. |
| Integrated synchronous rectification | Eliminates external Schottky diode, reduces conduction losses, and improves efficiency by ~8–12% vs. asynchronous boosters. |
| Internal soft start & compensation | Removes need for external SS capacitor or compensation network - cuts BOM count and simplifies layout validation. |
| Inrush current limiting | Two-stage PMOS linear charge (0.3 A → 0.8 A) prevents input voltage sag and protects weak sources like coin cells. |
| Power-save mode (PSM) | Frequency stretching at light loads reduces switching loss and maintains regulation without burst-mode noise. |
| Robust protection suite | OVP, SCP, OTP, and UVLO operate autonomously - no firmware or external monitoring required for field reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-up converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TPS61291DRVR | Lower IQ (1.2 µA), but max VOUT = 4.5 V and no true output disconnect; uses external diode. | Limited to ≤4.5 V rails; unsuitable where 5 V USB compliance or zero-output-leakage is mandatory. | Select if ultra-low shutdown current outweighs output voltage and disconnect requirements. |
| Analog Devices ADP1613ARMZ-R7 | Higher peak current (4 A), but no integrated PMOS disconnect, higher IQ (70 µA), and requires external compensation. | Needs external Schottky and compensation components; larger solution size and less robust short-circuit recovery. | Choose only when >3.6 A peak current is essential and board space is not constrained. |

FAQ
What is the minimum input voltage required for MP3414AGJ-P to start switching?
The MP3414AGJ-P starts up from as low as 1.8 V input, entering linear charge mode first to pre-charge the output before transitioning to 1 MHz PWM switching. This allows reliable operation from nearly-dead alkaline or NiMH cells and single-cell Li-ion down to 2.0 V.
Does MP3414AGJ-P require an external Schottky diode?
No - MP3414AGJ-P integrates both high-side PMOS and low-side NMOS synchronous rectifiers, eliminating the need for an external Schottky diode. Adding one would compromise the true output disconnect feature and increase conduction losses.
How is output voltage programmed on MP3414AGJ-P?
VOUT is set via a resistive divider from OUT to FB, using the internal 600 mV reference. For 5 V output, a common configuration uses R1 = 1 MΩ and R2 = 137 kΩ. R1 should stay between 499 kΩ and 1 MΩ to balance noise immunity and loop stability.
What happens during output short-circuit condition?
Under short-circuit, VOUT drops below VIN – 0.3 V, triggering automatic hiccup-mode recovery: the IC stops switching for ~50 µs, re-enters linear charge mode, and attempts restart under soft-start control until the fault clears.
Can MP3414AGJ-P operate with input voltage higher than output voltage?
No - MP3414AGJ-P is a boost-only converter. If VIN ≥ VOUT, the device cannot regulate and may enter undefined behavior or excessive ripple due to minimum on-time violation; it is not designed for buck-boost or pass-through operation.
Is thermal performance validated in the TSOT23-8 package?
Yes - the TSOT23-8 package has θJA = 100 °C/W on a 4-layer JEDEC PCB. At 1.25 W max power dissipation and 25 °C ambient, junction temperature stays below 150 °C. Internal thermal shutdown (155 °C) provides fail-safe protection.
What layout practices prevent EMI in MP3414AGJ-P designs?
Key practices include: placing 1 µF ceramic capacitor directly between OUT and PGND with minimal loop area; routing SW trace short/wide; separating AGND from PGND and connecting at single point; locating FB divider close to FB/AGND; and using wide copper pours with multiple vias for PGND thermal relief.
