Product details
Overview
MPM3593GQY-0001-T from Monolithic Power Systems is a digitally calibrated, synchronous step-down power module integrating high-side and low-side MOSFETs, I²C-configurable control, multi-page OTP memory, and full protection circuitry. It delivers up to 3A continuous output at ≤5V VOUT (2A at >5V), supports 3.5–45V input, and achieves 0.8–12V programmable output voltage with on-the-fly adjustment for industrial, automotive, and telecom DC/DC conversion.
For engineers reviewing the MPM3593GQY-0001-T datasheet, MPM3593GQY-0001-T pinout, MPM3593GQY-0001-T application, or MPM3593GQY-0001-T equivalent, this product enables rapid system-level optimization via I²C-adjusting switching frequency (250 kHz–2.5 MHz), soft-start time (0.5–4 ms), current limit (2–8 A), OVP thresholds, and thermal shutdown (125–175°C)-before permanently storing settings in OTP memory.
Technical Context
The MPM3593GQY-0001-T implements peak-current-mode PWM control with internal compensation, slope compensation, and configurable dead-time management. Its dual-mode operation-Advanced Asynchronous Modulation (AAM) for light-load efficiency and Forced Continuous Conduction Mode (FCCM) for low-noise fixed-frequency regulation-enables dynamic trade-off selection between efficiency and ripple performance.
It features an integrated 5V VCC LDO powered from VIN (or VOUT bias when enabled), configurable EN threshold (1.2–2 V), PG and /FT open-drain fault indicators, SYNCIN/SYNCO capability, and I²C-address setting via external resistor. All register-based parameters-including UVLO, OVP, soft-start slew rate (1–4 V/ns), and valley/peak current limits-are validated across –40°C to +150°C junction temperature.

| 1,2,3,4,36 | VOUT | Main regulated output node - connects directly to output capacitor bank and load; multiple pins reduce IR drop and improve current sharing. |
| 5,6 | BST | Bootstrap supply for HS-FET gate driver - requires internal 0.1 µF BST–SW capacitor; floating-capable for layout flexibility. |
| 7 | VCC | Internal 5V LDO output - powers logic and analog blocks; decoupled by internal 1 µF capacitor; supports VOUT bias mode when VOUT > 5V. |
| 8 | AGND | Signal ground reference - isolated from PGND internally; must be connected to power ground on PCB for noise immunity and accurate feedback sensing. |
| 9 | VOUT_S | Precision output voltage sense - enables remote sensing for improved load regulation; bypasses internal FB divider when used. |
| 10 | ADD | I²C address configuration - sets device address via external resistor to avoid bus conflicts in multi-module systems. |
| 11,12 | SYNC | Configurable sync interface - selectable as SYNCIN (for clock synchronization) or SYNCO (for master clock output) via I²C register. |
| 13–15,39 | VIN | Main input supply - multiple pins minimize trace inductance and reduce switching noise coupling into sensitive circuits. |
| 16–18,40 | PGND | Power ground return - tied to thermal pad; must connect to large copper area for thermal management and low-impedance return path. |
| 19,20 | EN | Enable control input - active-high digital enable; threshold configurable from 1.2 V to 2 V; must not be floated. |
| 21 | PG | Open-drain power-good indicator - asserts after VOUT reaches 86–92% of target and remains stable for ≥30 µs; used for system sequencing. |
| 22 | /FT | Open-drain fault indicator - pulled low on OVP, OCP, UVLO, or thermal shutdown; provides immediate system-level fault signaling. |
| 23 | SCL | I²C serial clock input - supports standard-mode (400 kHz) timing; rise/fall times specified for 400 pF bus capacitance. |
| 24 | SDA | I²C bidirectional data line - supports read/write access to all configuration registers and status flags. |
| 25,26,41 | SW | Switch node - internally connected to integrated inductor; high dv/dt node requiring tight layout and minimal loop area. |
| 27,35,38 | NC | No-connect - must remain unconnected and un-bonded on PCB; floating per datasheet requirement. |
Key Features
| Feature | Design Value |
|---|---|
| Digitally calibrated OTP storage | Multi-page one-time programmable memory retains I²C-configured settings (VOUT, fSW, OVP, soft-start, etc.) after power cycle - eliminates external EEPROM or firmware dependency. |
| Configurable light-load efficiency | AAM mode reduces quiescent current to ~1 µA in sleep state while maintaining fast wake-up; FCCM option preserves fixed-frequency operation for noise-sensitive loads. |
| Low-EMI design support | Frequency dithering, adjustable slew rate (1–4 V/ns), and SYNC capability enable compliance with CISPR 22/EN55022 Class B conducted/radiated emissions limits. |
| Integrated thermal and fault management | Programmable thermal shutdown (125–175°C) with 25–50°C hysteresis, plus independent OVP/OCP/UVLO thresholds - allows precise margining for safety-critical systems. |
| Flexible feedback architecture | Supports both internal FB divider (0.8–12V) and external resistor network with VOUT_S sense - enables precision regulation and compatibility with legacy designs. |

FAQ
What is the default output voltage and how is it set?
The MPM3593GQY-0001-T defaults to 5.0 V ±0.075 V (–40°C to +125°C) via internal factory-programmed OTP registers. This value is established during final test and cannot be altered without reprogramming OTP - which is irreversible. The default is confirmed by register 00h bits[7:0] = 0x64 and 01h bits[1:0] = 0b01 in the datasheet.
Can the I²C interface be used after power-up without enabling EN?
No. The I²C interface is disabled until the EN pin voltage exceeds 2 V, at which point the internal logic and I²C block are powered and accessible. Below 2 V, the I²C bus is blocked and all RAM registers reset to their OTP-stored defaults - ensuring deterministic behavior during brown-out or partial power conditions.
How does the VOUT_S pin affect regulation accuracy?
VOUT_S enables remote sensing by connecting directly to the load point, bypassing PCB trace resistance. When enabled, it overrides the internal FB divider and improves load regulation to ±0.1% (vs. ±0.3% with internal sensing), critical for high-precision analog or high-current digital loads where trace IR drop exceeds 10 mV.
Is the QFN-41 thermal pad electrically connected to PGND?
Yes. The exposed thermal pad on the QFN-41 package is internally bonded to PGND and must be soldered to a dedicated PGND copper pour on the PCB. This connection serves both thermal conduction (reducing θJA by ~10°C/W) and electrical grounding for the power stage - failure to connect degrades efficiency and may trigger thermal shutdown prematurely.
What happens during thermal shutdown and how is recovery managed?
When junction temperature reaches the programmed TSD threshold (default 175°C), the device halts switching, pulls /FT low, and holds PG low. Recovery occurs only after temperature falls below TSD minus hysteresis (default 25°C), at which point soft-start reinitiates. No external reset is needed - the behavior is fully autonomous and documented in register 07h bits[7:6] and bit[5].
Does the MPM3593GQY-0001-T support spread-spectrum frequency modulation?
No. It supports frequency dithering - a deterministic, bounded variation of fSW (±5–10% around center frequency) controlled via I²C register 03h bits[5:4] - which reduces peak EMI amplitude without introducing jitter into timing-critical systems. True spread-spectrum (SSFM) with random modulation is not implemented.
Can multiple MPM3593GQY-0001-T devices share the same I²C bus?
Yes, provided each device has a unique I²C address set via the ADD pin resistor. Up to eight devices can coexist on one bus (7-bit addressing, 0x60–0x67 range). Synchronization is also possible: one unit can drive SYNC as master (SYNCO), while others configure SYNC as slave (SYNCIN) to align switching edges and minimize beat frequencies.
