Product details
Overview
MPQ8636HGLE-10-P from Monolithic Power Systems is a 10A, 4.5V–18V input, synchronous step-down DC/DC converter in a 16-pin QFN (3mm×4mm) package with non-latch over-voltage protection, Constant-On-Time control, and 0.611V–13V adjustable output voltage. It delivers high efficiency across load range and supports fast transient response in telecom power supplies and server VRMs.
For engineers reviewing the MPQ8636HGLE-10-P datasheet, MPQ8636HGLE-10-P pinout, MPQ8636HGLE-10-P application, or MPQ8636HGLE-10-P equivalent, key selection factors include its 19.6mΩ high-side RDS(ON), 5.7mΩ low-side RDS(ON), 13–21.6A peak current limit, non-latch OVP mode, and programmable 200kHz–1MHz switching frequency via external resistor.
Technical Context
The MPQ8636HGLE-10-P implements adaptive Constant-On-Time (COT) control with feed-forward compensation via the FREQ pin, enabling stable operation across wide input voltage variation while maintaining near-constant switching frequency. Its internal 5V VCC LDO powers gate drivers and control logic, and the BST capacitor forms a floating supply for high-side MOSFET drive.
It operates exclusively in continuous conduction mode (CCM), with integrated dead-time control preventing shoot-through between high- and low-side MOSFETs. Protection includes non-latch over-current (valley-current sensing), non-latch over-voltage (130% VFB threshold), and thermal shutdown at 150°C with 25°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 10A continuous - supports mid-power point-of-load regulation in base station RF cards and CPU core rails. |
| Input Voltage Range | 4.5V to 18V - compatible with 5V, 12V, and 15V intermediate bus architectures without external pre-regulation. |
| Switching Frequency | 200kHz to 1MHz (programmable via RFREQ resistor) - enables trade-off between efficiency (lower fSW) and component size (higher fSW). |
| Reference Voltage | 611mV ±3mV (0°C to 70°C) - sets output accuracy baseline; enables 0.611V–13V adjustment via external resistor divider. |
| High-Side RDS(ON) | 19.6mΩ @ TJ = 25°C - reduces conduction loss at 10A, contributing to >92% peak efficiency at 12VIN/1VOUT. |
| Low-Side RDS(ON) | 5.7mΩ @ TJ = 25°C - minimizes synchronous rectification loss during off-time, critical for light-load efficiency. |
| OVP Mode | Non-latch - recovers automatically after fault clears, suitable for systems requiring self-recovery without host intervention. |
Pinout & Package
MPQ8636HGLE-10-P uses a thermally enhanced 16-pin QFN package (3mm × 4mm, 0.5mm pitch) with exposed thermal pad (EP) on underside for PCB heat dissipation. Pin 1 is marked by dot or chamfered corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 EN | Enable control input | Digital logic-level input (1.3V typical threshold); must be pulled up or driven - floating causes undefined operation. |
| 2 FREQ | Frequency programming node | Resistor-connected to IN sets ON-time; feed-forward stabilizes fSW vs. VIN variation. |
| 3 FB | Feedback voltage sense | Monitors output via resistor divider; also triggers OVP at 130% VFB; requires short, low-noise trace layout. |
| 4 SS | Soft-start timing node | External capacitor sets startup ramp time; prevents inrush current and overshoot during power-up. |
| 5 AGND | Analog ground reference | Separate ground for control circuitry; must be star-connected to PGND near IC to avoid noise coupling. |
| 6 PG | Open-drain power-good signal | Asserts HIGH when VOUT ≥ 91% nominal; requires external 100kΩ pull-up; 2ms delay ensures stable regulation. |
| 7 VCC | Internal 5V LDO output | Powers gate drivers and bias circuits; requires ≥1µF X7R/X5R ceramic decoupling close to pin. |
| 8 BST | Bootstrap supply node | Connects to SW via 0.1µF ceramic capacitor; provides floating gate drive voltage for high-side MOSFET. |
| 9,14 IN | Main power input | 4.5V–18V supply rail; requires low-ESR bulk and ceramic input capacitors; wide copper pour recommended. |
| 10,11,12,13 PGND | Power ground return | High-current return path for SW and IN; must be low-inductance plane connected directly to EP pad. |
| 15,16 SW | Switch node | Drives external inductor; experiences high dV/dt; requires tight loop layout with minimal trace length and vias. |
Key Features
| Feature | Design Value |
|---|---|
| Proprietary switching-loss reduction | Optimized gate drive timing and internal MOSFET pairing reduce turn-on/turn-off energy loss at 1MHz. |
| Adaptive COT control | Eliminates external compensation network; maintains stability across input/output/load variations without tuning. |
| Pre-bias start-up | Allows safe startup into pre-charged output capacitors without reverse current or latch-up risk. |
| Programmable soft-start | Adjustable ramp time via external SS capacitor prevents output overshoot and inrush stress on downstream loads. |
| Non-latch OCP/OVP/thermal shutdown | Auto-recovery after fault clearance avoids system lockup; eliminates need for external reset circuitry. |
Applications
| Telecom Base Station RF Cards | Server CPU Core Power Rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ8636GLE-10 | Latch-off OVP instead of non-latch; identical RDS(ON), current limits, and package. | Suitable where fault isolation is prioritized over auto-recovery (e.g., safety-critical subsystems). | Select MPQ8636GLE-10 only if system architecture requires latched shutdown on OVP event. |
| RTQ2132BGQW | 12A rated, 2.7V–18V input, fixed 500kHz fSW, no FREQ pin; uses current-mode control. | Better suited for designs needing higher current headroom and fixed-frequency EMI control, but lacks programmable fSW and soft-start. | Choose RTQ2132BGQW when 12A margin and deterministic switching frequency outweigh flexibility in frequency and startup control. |
Compared with MPQ8636GLE-10, MPQ8636HGLE-10 offers automatic OVP recovery essential for unattended telecom equipment; versus RTQ2132BGQW, it trades fixed-frequency predictability for broader design adaptability via COT and resistor-programmed frequency.

FAQ
What is the difference between MPQ8636HGLE-10 and MPQ8636GLE-10?
The MPQ8636HGLE-10 features non-latch over-voltage protection (OVP), allowing automatic recovery once the fault condition clears, whereas MPQ8636GLE-10 uses latch-off OVP requiring an enable-cycle reset. All other electrical specs-including RDS(ON), current limits, package, and pinout-are identical. This distinction directly impacts system fault-handling strategy.
Can MPQ8636HGLE-10 operate with a 24V input?
No. The absolute maximum input voltage is 21V, and the recommended operating range is strictly 4.5V to 18V. Applying 24V exceeds the VIN rating and risks permanent damage to the internal MOSFETs and control circuitry. A front-end pre-regulator or clamp circuit is required for 24V bus compatibility.
What is the minimum output voltage achievable with MPQ8636HGLE-10?
The minimum regulated output voltage is 0.611V, set by the internal 611mV reference voltage and achieved using a standard resistor divider on the FB pin. Output voltages below this value cannot be stably regulated due to feedback loop limitations and reference tolerance.
How is switching frequency programmed, and what resistor value yields 500kHz?
Switching frequency is set by connecting a resistor (RFREQ) between the FREQ pin and the IN pin. For 500kHz at VIN = 12V, RFREQ ≈ 249kΩ (calculated per datasheet Equation 2). Frequency remains stable across input voltage variation due to feed-forward compensation.
Does MPQ8636HGLE-10 support forced PWM mode or DCM operation?
No. MPQ8636HGLE-10 operates exclusively in continuous conduction mode (CCM) and does not support forced PWM or discontinuous conduction mode (DCM). Light-load efficiency is maintained via low quiescent current (860µA typ.) and optimized MOSFET RDS(ON), not mode switching.
Is the thermal pad (EP) electrically connected internally?
Yes. The exposed thermal pad is internally connected to PGND and must be soldered to a dedicated PCB thermal plane tied to the PGND net. Failure to connect the EP compromises thermal performance and may trigger premature thermal shutdown under 10A load.
What is the purpose of the BST capacitor, and what value is recommended?
The BST capacitor (typically 0.1µF X7R ceramic) forms a floating voltage source for the high-side gate driver. It charges through the internal diode when SW is low and supplies gate drive voltage when SW is high. Must be placed within 2mm of BST/SW pins with low-inductance layout to prevent gate drive instability.
