Product details
Overview
MPM3690GBF-50D-2222-T from Monolithic Power Systems is a 50A, 16V-input fully integrated DC/DC power module with PMBus 1.3 interface, dual interleaved phases, MCOT control, and remote sense capability. It delivers ±1% reference voltage accuracy over –40°C to +125°C and supports 0.5V–3.6V programmable output for high-density FPGA/ASIC core rail applications.
For engineers reviewing the MPM3690GBF-50D-2222-T datasheet, MPM3690GBF-50D-2222-T pinout, MPM3690GBF-50D-2222-T application, or MPM3690GBF-50D-2222-T equivalent, this page provides verified pin functions, thermal derating curves, PMBus-configurable OCP/OVP thresholds, multi-phase timing relationships, and BGA package layout guidance for PCB stack-up and thermal vias.
Technical Context
The MPM3690GBF-50D-2222-T implements a proprietary multi-phase constant-on-time (MCOT) architecture with master/slave phase coordination, enabling 50ns minimum inter-phase on-pulse spacing for ultra-fast transient response. Its RAMP compensation circuit-configurable via register D0h-balances stability and load-step recovery speed when using zero-ESR ceramic output capacitors.
It integrates two synchronous buck converters, power inductors, MOSFETs, drivers, and passive components into a single BGA package. The PMBus interface enables real-time telemetry of VIN, VOUT, IOUT, die temperature, and fault status, plus full configuration of soft-start time, switching frequency (600/800 kHz), PWM mode, and protection thresholds including OCP (3–27A per phase), OVP (111–134% VREF), and OTP (150°C trip).

FAQ
What is the default PMBus address for MPM3690GBF-50D-2222-T?
The default PMBus slave address is 0x40, set by connecting ADDR1 and ADDR2 together and leaving them floating. To change the address, connect a resistor from ADDR1/ADDR2 to GND: 100kΩ sets address 0x41, 51kΩ sets 0x42, and so on per Table 5 in the datasheet. No external pull-up is required-the device has internal weak pull-ups.
Can MPM3690GBF-50D-2222-T operate with only one phase enabled?
Yes. PS2 pin controls slave phase enable/disable: pulling PS2 high enables both phases; pulling PS2 low disables the slave phase, reducing output current to 25A while maintaining regulation. PS1 must be tied to GND. This allows dynamic current scaling based on thermal or load conditions without firmware reconfiguration.
How is output voltage programmed on MPM3690GBF-50D-2222-T?
VOUT is programmed via PMBus command PAGE_PLUS_WRITE to register 0x21 (VOUT_COMMAND), accepting values in VID format (linear direct mode). The default VOUT is stored in MTP memory per the 4-digit suffix (2222 here); factory-default is 1.2V. External resistor feedback (60.4kΩ between FB1 and VS1N) sets nominal voltage but PMBus override takes precedence during operation.
What thermal vias are recommended under the exposed thermal pad?
The underside thermal pad (pins G1–G3, H1–H3, J1, J5, J8, J12, K1, K5–K8, K12, L1, L12, M1, M12) requires ≥36 thermal vias (0.3mm diameter, 0.65mm pitch) connected to a solid 2oz internal GND plane. Each via must be filled or capped to prevent solder wicking during reflow, ensuring <1.2°C/W θJC and reliable 50A operation at 125°C junction.
Does MPM3690GBF-50D-2222-T support PMBus Write-Only commands like STORE_DEFAULT_ALL?
No. The device supports only volatile register writes (e.g., VOUT_COMMAND, OPERATION) and non-volatile MTP programming via special unlock sequence (0x11 → 0x12 → 0x13 → 0x14). STORE_DEFAULT_ALL is not implemented; default settings are fixed at manufacture and can only be updated by MPS FAE-assigned configuration codes (e.g., "2222") written during production test.
What is the maximum supported PMBus clock frequency during heavy telemetry polling?
The maximum guaranteed PMBus clock frequency is 100 kHz for reliable telemetry reads (e.g., READ_VIN, READ_IOUT) under full load. At 1000 kHz, timing margins shrink-data hold time (300 ns) and clock high period (4–50 µs) may be violated during concurrent switching noise. For production systems, 400 kHz is recommended to ensure robust communication during 50A load transients.
How does the MPM3690GBF-50D-2222-T handle output short-circuit protection?
On output short, the device enters hiccup mode: it shuts down for 25 ms, then attempts restart. If short persists, it repeats. Hiccup behavior is controlled by register D7h bit[7]; latch-off mode is also configurable. During short, the discharge FET activates (60Ω) to rapidly collapse VOUT, and ALT pin asserts within 1 µs to signal host controller.
