Product details
Overview
MP3216GJE-P from Monolithic Power Systems is a 36V, 1.3MHz step-up DC-DC converter with integrated 0.75A/0.6Ω N-channel power switch and output disconnect capability. It regulates output voltage via fixed-frequency current-mode control, supports 2.5–6V input, delivers up to 36V output, and features cycle-by-cycle overcurrent protection, UVLO (2.45V), and thermal shutdown. Used in portable digital still cameras for high-voltage flash charging.
For engineers reviewing the MP3216GJE-P datasheet, MP3216GJE-P pinout, MP3216GJE-P application, or MP3216GJE-P equivalent, key selection criteria include its TSOT23-5 package footprint, 1.3MHz switching frequency for compact magnetics, 1.24V feedback reference accuracy, output disconnect function for system-level power sequencing, and 42V overvoltage shutdown threshold.
Technical Context
The MP3216GJE-P implements a constant-frequency peak-current-mode boost architecture with internal compensation. Its error amplifier compares FB voltage against a 1.24V reference, generating a control signal that modulates the 0.75A power switch duty cycle to maintain regulation.
Unlike the TSOT23-6 variant (MP3216DJ), the TSOT23-5 version omits the dedicated L pin and internal N-channel disconnect switch - thus providing output disconnect only via external circuitry or EN-controlled shutdown, not active MOSFET-based load isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 6V - Matches single-cell Li-ion or USB-powered systems without external LDO pre-regulation. |
| Switching Frequency | 1.3MHz (typ) - Enables use of sub-3.3µH inductors and reduces EMI fundamental frequency above AM band. |
| Feedback Reference | 1.24V ±0.04V - Enables precise output setting (e.g., 33V with 133kΩ/5.1kΩ divider) with <±1% VOUT error at room temperature. |
| Power Switch RDS(on) | 600mΩ (max) - Limits conduction loss to ≤270mW at 0.75A, supporting >85% efficiency at 10mA–100mA loads. |
| Overvoltage Threshold | 42V - Protects downstream components (e.g., flash LEDs, capacitors) during open-feedback or resistor-divider fault conditions. |
| Enable Threshold | 2.0V (ON), 0.8V (OFF) - Compatible with standard GPIO logic levels and allows direct connection to microcontroller I/O pins. |
| Quiescent Current | 550–650µA - Minimizes battery drain in standby mode for portable devices requiring long shelf life. |
Pinout & Package
MP3216GJE-P is housed in a RoHS-compliant, lead-free TSOT23-5 package (1.6mm × 2.9mm × 0.9mm), optimized for space-constrained portable designs. Pin 1 is SW (switch node), Pin 2 is GND, Pin 3 is FB (feedback), Pin 4 is EN (enable), and Pin 5 is IN (input supply).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - SW | Drain of internal 0.75A N-MOSFET | Connects to inductor and Schottky diode anode; carries high dv/dt switching node - requires tight layout to minimize EMI and ringing. |
| 2 - GND | Power and signal ground reference | Must be low-impedance return path for SW, IN, and FB; tie local ceramic bypass caps directly to this pin. |
| 3 - FB | Inverting input of error amplifier | Senses output via resistive divider; 70nA bias current enables use of high-value resistors (e.g., 133kΩ/5.1kΩ) without significant error. |
| 4 - EN | Logic-controlled enable input | Active-high interface: ≥2V enables regulation; ≤0.8V forces shutdown with 10µA quiescent draw - supports system-level power sequencing. |
| 5 - IN | Input supply connection | Accepts 2.5–6V; requires local 4.7µF ceramic bypass capacitor placed adjacent to pin to suppress input ripple and EMI. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed 1.3MHz switching frequency | Enables consistent EMI filtering design and eliminates need for external frequency programming components. |
| Integrated 0.6Ω power MOSFET | Eliminates external high-side switch, reducing BOM count and PCB area while maintaining 0.75A current capability. |
| Output disconnect support (via EN control) | Allows full system power-down by disabling regulator and isolating output from input - critical for low-power sleep modes. |
| 42V overvoltage shutdown | Prevents catastrophic failure during feedback loop open-circuit faults, protecting external capacitors and LED strings. |
| Thermal shutdown + UVLO | Provides dual-layer protection: UVLO prevents startup below 2.45V (avoiding brownout instability); thermal shutdown disables operation above 150°C. |
Applications
| Digital Still Camera Flash Charging | Portable Medical Sensor Bias Supply |
|---|---|
Use Scenario: Charging a 33V xenon flash capacitor from a 5V USB source in under 1 second. IC Role / Device Role / Timing Role: Step-up converter with fast transient response and precise output regulation to meet camera shutter timing constraints.

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP3216DJ | TSOT23-6 package with dedicated L pin and integrated N-MOSFET for true output disconnect; includes inrush current limiting (210mA). | Required when active load isolation (not just shutdown) is needed - e.g., preventing backfeed into input during fault conditions. | Select MP3216DJ if board layout permits 6-pin footprint and true output disconnection is mandatory for safety or sequencing compliance. |
| TPS61088RHLR | Higher 2.2A switch current, 2.7–12V input, 1.1MHz fSW, no integrated output disconnect; requires external MOSFET for load isolation. | Better suited for higher-output-current applications (>100mA) but lacks native disconnect - adds complexity and component count. | Choose TPS61088RHLR only when >0.75A output current is required and external disconnect can be accommodated in design. |
Compared with MP3216DJ, MP3216GJE-P trades output disconnect functionality for smaller size and lower cost - ideal for space-limited applications where EN-controlled shutdown suffices. Versus TPS61088RHLR, it offers tighter feedback accuracy and simpler layout at lower current capability.

FAQ
What is the maximum achievable output voltage with MP3216GJE-P?
The MP3216GJE-P supports up to 36V output voltage under normal operation. Its overvoltage protection triggers at 42V, permanently disabling switching until power is cycled. Output voltage is set externally via the FB resistive divider; typical configurations reach 24V–33V for flash and sensor bias applications.
Does MP3216GJE-P provide true output disconnect like MP3216DJ?
No. MP3216GJE-P uses a TSOT23-5 package and lacks the dedicated L pin and internal N-channel disconnect MOSFET found in the TSOT23-6 MP3216DJ. It achieves output isolation only through EN-driven shutdown - the output remains electrically connected to the inductor and diode during disable, unlike active MOSFET-based disconnection.
Can MP3216GJE-P operate from a 3.3V input source?
Yes. The MP3216GJE-P operates across 2.5V to 6V input, making it compatible with 3.3V sources such as regulated LDO outputs or partially discharged Li-ion cells. At 3.3V input, it can still deliver 33V output with appropriate inductor and diode selection, though efficiency decreases slightly versus 5V operation.
What is the recommended output capacitor for stable 33V operation?
For 33V output at 10mA load, a 10µF X7R ceramic capacitor with 25V+ rating is recommended. Ceramic is preferred for low ESR and stability; tantalum or polymer capacitors may be used if higher capacitance is needed, but must be rated for ≥33V working voltage and verified for loop stability per the datasheet's compensation guidelines.
Is MP3216GJE-P pin-compatible with other MPS boost converters?
No. MP3216GJE-P has a unique 5-pin TSOT23-5 pinout (SW-GND-FB-EN-IN). It is not pin-compatible with MP3216DJ (6-pin) or other MPS boost ICs like MP3431 or MP9186. Layout must be designed specifically for its pin assignment and thermal pad configuration (no exposed pad in TSOT23-5).
How does the 1.24V feedback reference improve design flexibility?
The tightly specified 1.24V ±0.04V reference enables accurate output voltage setting using standard 1% resistors. For example, a 133kΩ/5.1kΩ divider yields 33.0V with <±0.5% error - eliminating need for trimming or calibration in production, and simplifying BOM by avoiding precision reference ICs.
What layout practices are critical for MP3216GJE-P EMI performance?
Minimize SW node loop area by placing inductor, diode, and input/output capacitors adjacent to the IC. Route FB trace away from noisy nodes and shield it with ground guard traces. Connect GND pins directly to a solid ground plane; place 4.7µF input cap within 2mm of IN pin and 0.1µF cap near L (if used) or SW. Avoid vias in high-current paths.
