Product details
Overview
MP8762GLE-Z from Monolithic Power Systems is a fully integrated synchronous step-down DC/DC converter delivering 10A output current with 2.5V–18V input range (external 5V bias) or 4.5V–18V (internal bias), 0.611V–13V adjustable output, and programmable 200kHz–1MHz switching frequency via FREQ pin resistor. It employs adaptive Constant-On-Time (COT) control for ultrafast transient response and operates in QFN-16 (3mm×4mm) package with integrated high-side (21mΩ) and low-side (7mΩ) MOSFETs. Used in flat-panel TV power rails requiring tight regulation and fast load-step immunity.
For engineers reviewing the MP8762GLE-Z datasheet, MP8762GLE-Z pinout, MP8762GLE-Z application, or MP8762GLE-Z equivalent, key selection criteria include its COT-based transient performance, dual-bias operation flexibility, non-latch OCP/OVP/thermal shutdown, pre-bias startup capability, and soft-start programmability via external capacitor - all critical for distributed power systems and set-top box designs.
Technical Context
The MP8762GLE-Z implements adaptive Constant-On-Time (COT) control with feed-forward compensation, enabling near-constant switching frequency across input voltage variation and eliminating need for external compensation components. Its internal 4.8V VCC LDO powers control circuitry, while external 5V bias disables the LDO to extend VIN down to 2.5V.
It integrates dual N-channel MOSFETs (HS RDS(ON) = 21mΩ, LS RDS(ON) = 7mΩ), supports pre-bias startup, and delivers power-good signaling with 2.5ms delay and 91% VFB rising threshold. Protection includes non-latch over-current (peak/valley/negative), over-voltage (120% VFB non-latch, 130% latch), and thermal shutdown at 150°C.

Pinout & Package
MP8762GLE-Z is housed in a thermally enhanced 16-pin QFN package (3mm × 4mm, 0.5mm pitch), optimized for new designs per MPS documentation. The exposed thermal pad (Pin 15/16 PGND) must be soldered to PCB ground plane for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 1) | Enable control input | Digital logic-level input; pull-up to IN sets automatic startup voltage; internal zener clamp limits to 6V |
| FREQ (Pin 2) | Frequency programming node | Resistor to IN sets CCM switching frequency; enables feed-forward compensation for input-voltage-invariant timing |
| FB (Pin 3) | Feedback sensing input | Monitors output via resistor divider; reference is 611mV ±1%; layout sensitivity requires short trace and no vias |
| SS (Pin 4) | Soft-start timing node | 20µA internal current source charges external capacitor; controls output ramp rate to avoid inrush-triggered OCP |
| AGND (Pin 5) | Analog ground reference | Separate ground for control circuitry; must be star-connected to PGND near IC to minimize noise coupling |
| PG (Pin 6) | Open-drain power-good indicator | Pulled low until FB ≥91% VREF + 2.5ms delay; sinks 4mA at 0.4V - requires external pull-up to ≤5.5V |
| VCC (Pin 7) | Internal LDO output | 4.8V regulated supply for gate drivers/control logic; decoupled with ≥1µF X7R/X5R ceramic; disabled by external 5V bias |
| BST (Pin 8) | Bootstrap supply for HS gate driver | Requires 0.1µF ceramic capacitor between BST and SW; enables high-side NMOS drive above VIN rail |
| SW (Pins 9,14) | Power switch node | Connects to inductor and BST cap; swings from ~–1V (due to LS body diode) to VIN; requires wide copper pour |
| PGND (Pins 10,11,12,13) | Power ground return | Low-impedance path for inductor current and MOSFET conduction; must be solidly connected to thermal pad and input/output caps |
| IN (Pin 15) | Main input supply | Accepts 2.5V–18V (with 5V bias) or 4.5V–18V (with internal VCC); requires local 10µF+ ceramic input capacitance |

|---|---|
| Adaptive COT Control | Delivers <5µs load-step response without external compensation; maintains stability across line/load/temperature |
| Integrated Dual MOSFETs | 21mΩ HS + 7mΩ LS RDS(ON) reduces conduction loss and eliminates discrete FET selection and layout complexity |
| Pre-Bias Startup | Enables monotonic rise into pre-charged outputs - essential for hot-swap and multi-rail sequencing applications |
| Programmable Soft Start | External capacitor sets ramp time; prevents overshoot and avoids current-limit tripping during power-up |
| Dual Bias Operation Mode | Supports 2.5V min VIN with external 5V bias or 4.5V min with internal VCC - increases system-level design flexibility |
| Non-Latch Fault Protection | OCP, OVP, and thermal shutdown auto-recover after fault clears - avoids system lockup in transient overload events |

FAQ
What is the minimum input voltage supported by MP8762GLE-Z?
The MP8762GLE-Z supports 2.5V minimum input voltage when an external 5V bias is applied to VCC, bypassing the internal LDO. With internal VCC bias only, the minimum input is 4.5V due to the 3.8V VCC UVLO threshold. This dual-bias architecture allows designers to extend low-input operation without sacrificing regulation stability.
Does MP8762GLE-Z support pre-biased output startup?
Yes - MP8762GLE-Z features monotonic pre-bias startup. When the FB pin senses a pre-charged output voltage at power-on, the IC holds both high-side and low-side MOSFETs off until the soft-start capacitor voltage exceeds the sensed FB voltage, then ramps output smoothly without reverse current or output collapse.
How is switching frequency programmed on MP8762GLE-Z?
Switching frequency is set by connecting a resistor (RFREQ) between the FREQ pin and the IN pin. The value determines on-time via feed-forward compensation: FSW ≈ 6.1 × RFREQ(kΩ) × VIN(V) / 0.4. For example, a 453kΩ resistor yields ~250kHz at VIN=12V. Frequency remains stable across VIN variation due to this architecture.
What is the purpose of the AGND and PGND separation?
AGND serves as the quiet reference for feedback, soft-start, and enable circuitry; PGND carries high di/dt inductor return current. Separating them prevents noise coupling into sensitive analog nodes. They must be joined at a single point near the IC's thermal pad to maintain low-impedance power return while preserving signal integrity.
Can MP8762GLE-Z operate without an external soft-start capacitor?
No - the SS pin requires an external capacitor to control ramp time. Without it, the internal 20µA current source has no capacitance to charge, causing uncontrolled output rise and immediate OCP triggering. Typical values range from 1nF (1ms ramp) to 100nF (100ms ramp), selected based on output capacitance and load characteristics.
Is MP8762GLE-Z pin-compatible with MP8762GL-Z?
No - MP8762GLE-Z uses a 16-pin QFN (3mm×4mm) package with dedicated PGND pins (10,11,12,13) and separated IN/SW pins, whereas MP8762GL-Z is a 13-pin variant with merged functions and different pinout. MPS explicitly recommends the 16-pin version for new designs due to improved thermal and EMI performance.
What does the "Z" suffix indicate in MP8762GLE-Z?
The "Z" suffix denotes tape-and-reel packaging per MPS ordering conventions. MP8762GLE-Z is supplied in standard 3,000-unit reels compatible with automated SMT placement equipment, with moisture sensitivity level (MSL) 3 and Pb-free, halogen-free, RoHS-compliant construction.
