Product details
Overview
MP3216GJE-Z from Monolithic Power Systems is a 36V, 1.3MHz step-up DC-DC converter with integrated 0.75A/0.6Ω power MOSFET, output disconnect capability, and cycle-by-cycle current limiting. It regulates output voltage via fixed-frequency current-mode control and supports up to 33V output in portable boost applications with 5V input.
For engineers reviewing the MP3216GJE-Z datasheet, MP3216GJE-Z pinout, MP3216GJE-Z application, or MP3216GJE-Z equivalent, key selection criteria include input voltage range (2.5–6V), output disconnect function, 42V overvoltage shutdown threshold, thermal/UVLO protection, and TSOT23-5 package compatibility with space-constrained designs.
Technical Context
The MP3216GJE-Z implements a constant-frequency peak-current-mode boost architecture with internal 1.24V reference and error amplifier driving PWM comparator. A stabilizing ramp prevents subharmonic oscillation above 50% duty cycle, enabling stable regulation across wide load and input ranges.
It integrates under-voltage lockout (2.45V turn-on, 92mV hysteresis), 42V overvoltage shutdown, thermal shutdown at 150°C, and output short-circuit protection-though short-protection is only active in the TSOT23-6 variant (MP3216DJ), not in the TSOT23-5 MP3216GJE-Z.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 6V - Supports single-cell Li-ion, dual-cell alkaline, or USB-powered systems without external LDO pre-regulation. |
| Switching Frequency | 1.3MHz (typ) - Enables use of small, low-profile inductors (e.g., 2.2–33µH) and reduces EMI filtering burden. |
| Output Voltage Range | Up to 36V - Programmable via external resistor divider; suitable for white LED strings, PMOLED bias, or sensor excitation rails. |
| Internal Switch | 0.75A current limit, 0.6Ω RDS(on) - Limits peak inductor current and conduction loss; defines max deliverable power at given VIN/VOUT. |
| Feedback Reference | 1.24V ±4% - Sets output accuracy; used with standard resistor divider (e.g., 5.1kΩ + 133kΩ for 33V). |
| Enable Threshold | 2.0V (ON), 0.8V (OFF) - Compatible with 1.8V/3.3V logic; allows direct microcontroller GPIO control without level-shifting. |
| Quiescent Current | 550–650µA - Minimizes standby power draw in battery-operated devices during light-load or sleep modes. |
Pinout & Package
MP3216GJE-Z is housed in a RoHS-compliant, lead-free TSOT23-5 surface-mount package (1.6mm × 2.9mm × 0.9mm), optimized for high-density portable PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - SW | Power switch drain | Connects to inductor and Schottky diode anode; carries high-frequency switching current and must be routed with minimal loop area. |
| 2 - GND | Analog/digital ground | Primary return path for IC core, feedback network, and power stage; requires low-impedance connection to power plane. |
| 3 - FB | Feedback input | Senses divided output voltage; 1.24V reference sets regulation point; sensitive to noise-keep trace short and away from SW node. |
| 4 - EN | Enable control input | Logic-level ON/OFF control; internal pull-down ensures default-off state if left floating; no external pull-up required. |
| 5 - IN | Input supply | Connects to input source (2.5–6V); requires local 4.7µF ceramic bypass capacitor placed adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 0.6Ω MOSFET switch | Reduces external component count and board area; eliminates need for discrete high-side switch in boost topology. |
| Output disconnect function | Prevents reverse current flow from output to input when disabled-critical for battery-backed systems to avoid drain during shutdown. |
| Fixed 1.3MHz switching frequency | Enables consistent EMI profile and predictable filter design; avoids audible noise and simplifies compliance testing. |
| 42V overvoltage shutdown | Protects downstream components (e.g., LEDs, sensors) from catastrophic failure due to feedback resistor open-circuit or misconfiguration. |
| Thermal and UVLO protection | Ensures safe operation under overload, ambient temperature extremes, or brown-out conditions without external supervision circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP3421GJ-Z | Higher 2.2MHz switching frequency; 1A switch; no output disconnect; TSOT23-6 only | Lacks output disconnect; requires external high-side switch for reverse current blocking | Preferred where higher efficiency at light loads or smaller inductors are prioritized over output isolation. |
| TPS61088RHLR | 4.5A switch; 2.5–12V input; 5.5–23V output; no output disconnect; WQFN-16 package | Higher current capability but larger footprint and no built-in disconnect; requires external MOSFET for isolation | Selected when >1A output current is needed and board space permits larger package and added components. |
Compared with MP3216GJE-Z, MP3421GJ-Z trades output disconnect for higher switching frequency and current, while TPS61088RHLR offers greater power delivery at the cost of size, complexity, and loss of integrated isolation-making MP3216GJE-Z optimal for space-constrained, battery-sensitive boost applications requiring true input-output decoupling.

FAQ
What is the maximum output voltage achievable with MP3216GJE-Z?
The MP3216GJE-Z supports output voltages up to 36V, limited by its 42V overvoltage shutdown threshold. Output is set externally via resistor divider on FB pin; for example, 133kΩ/5.1kΩ yields ~33V. Exceeding 36V risks triggering OVP and disabling regulation.
Does MP3216GJE-Z provide output short-circuit protection?
No-output short-circuit protection is implemented only in the TSOT23-6 variant (MP3216DJ). The TSOT23-5 MP3216GJE-Z lacks the dedicated L pin and internal N-MOSFET required for inductor current limiting during short events.
Can MP3216GJE-Z operate with a 2.5V input from a single alkaline cell?
Yes-its 2.5V minimum input rating allows direct operation from fresh single-cell alkaline (1.5V nominal, up to 1.65V per cell) in series configurations or boosted LiFePO₄ cells. UVLO releases at 2.45V, ensuring reliable startup before significant voltage sag.
Is an external Schottky diode required, and what specifications are recommended?
Yes-an external Schottky diode is mandatory. Select one rated ≥36V reverse voltage (e.g., B0540), with average current rating exceeding max load and peak current rating >0.75A. Low forward voltage (<0.4V) and fast recovery (<10ns) minimize conduction and switching losses.
How does the output disconnect feature function in MP3216GJE-Z?
When EN = LOW, the internal N-channel MOSFET between IN and the power path is turned OFF, breaking the DC path from input to output. This prevents reverse current flow and battery drain-critical for systems where output capacitors remain charged after shutdown.
What is the recommended inductor value for 5V-to-33V conversion at 10mA load?
A 10µH to 22µH shielded power inductor with ≥1A saturation current is recommended. At 10mA load and 1.3MHz switching, this balances low ripple, minimal size, and avoidance of sub-harmonic instability-verified in MPS typical application circuit (Fig. 3).
Does MP3216GJE-Z require a minimum load to maintain regulation stability?
No-it maintains stable regulation down to zero load. Its current-mode control and internal compensation eliminate need for minimum load resistors, making it suitable for intermittent-duty applications like sensor biasing or flash charging.
