Monolithic Power Systems Inc. MPM3807CGLE-18-AEC1-Z

Overview

MPM3807CGLE-18-AEC1-Z from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified, fully integrated synchronous step-down power module with internal MOSFETs and inductor, delivering 1.8V fixed output at up to 2A continuous current from a 2.5V–5.5V input. It employs constant-on-time (COT) control with forced continuous conduction mode (FCCM), operates at 2.4MHz, and features power good (PG), enable (EN), soft-start (SS), and output discharge for automotive ADAS camera modules.

Technical Context

The MPM3807CGLE-18-AEC1-Z implements input-voltage feed-forward COT control with fixed minimum off-time (80ns) and 100% duty cycle capability, enabling stable regulation across its full 2.5V–5.5V input range while maintaining near-constant 2.4MHz switching frequency. Its internal 470nH inductor and matched 70mΩ/40mΩ PCH/NCH MOSFETs are co-optimized for low ripple and fast transient response.

Fault management includes cycle-by-cycle peak current limiting (3.5A), valley current limiting (2A), hiccup-mode short-circuit protection, thermal shutdown at 170°C, and output over-voltage protection triggered at 115% of 0.6V reference. The PG signal asserts high when FB exceeds 90% of VREF and deasserts at 85%, with 80µs deglitch timing.

FAQ

What is the recommended input capacitor for MPM3807CGLE-18-AEC1-Z?

A 10µF X5R or X7R ceramic capacitor placed within 2mm of the VIN and GND pins is required to suppress high-frequency switching noise and prevent input voltage droop during load transients. Additional bulk capacitance (e.g., 47µF tantalum) may be added upstream for low-frequency hold-up, but the 10µF local cap is mandatory per datasheet Figure 1 layout guidelines.

Can MPM3807CGLE-18-AEC1-Z operate with a 2.5V input and deliver full 2A at 1.8V?

Yes - the device supports 2.5V–5.5V input and maintains 2A continuous output across the full range, including at 2.5V input. At VIN = 2.5V, efficiency drops to ~82% (per Figure 11), but thermal rise remains within spec due to the 100% duty cycle capability and low RDS(ON) MOSFETs.

Is external compensation required for stability?

No - the MPM3807CGLE-18-AEC1-Z integrates a complete compensation network, including error amplifier, ramp generator, and internal RC components. No external compensation components are needed, simplifying design and eliminating tuning iterations.

How does the output discharge function behave during shutdown?

When EN is pulled low, the internal discharge MOSFET activates between OUT_S and GND, providing a ~150Ω path to safely bleed residual charge from the output capacitor. This prevents latch-up in downstream logic and enables clean power sequencing - unless blocked by an external capacitor between OUT and OUT_S per datasheet Section 8.5.

What is the thermal performance on a standard 4-layer PCB?

On MPS's reference EVB (6.3cm × 6.3cm, 4-layer, 2oz copper), θJC is 10°C/W and case temperature rise is ≤15°C at 2A/1.8V/5V input (per Figure 11). With proper thermal pad soldering and 6+ vias to inner ground planes, junction temperature stays below 120°C at full load and 85°C ambient.

Does the PG pin require a pull-up resistor?

Yes - PG is open-drain and must be pulled up to a voltage source (VIN or separate rail) via a 10kΩ–100kΩ resistor. Without pull-up, PG cannot assert high to indicate valid regulation. The datasheet specifies <400Ω maximum RDS(ON) for reliable low-state drive when pulled to GND.

Is the 1.8V output trimmed at final test?

Yes - the fixed 1.8V version undergoes post-package trimming to achieve ±1.2% tolerance over temperature (1.764V–1.836V), as confirmed in Electrical Characteristics Table (page 6). This eliminates need for external feedback calibration in production.
