PRODUCT OVERVIEW

What Is the MP8795GLE-P?

MP8795GLE-P is a fully integrated, high-frequency, synchronous step-down converter from Monolithic Power Systems (MPS) that offers a very compact solution for achieving up to 15A of continuous output current with excellent load and line regulation over a wide input supply range. The device is part of the MP8795 family, with the "-P" and "-Z" suffixes indicating different reel sizes for the same part.

The MP8795 adopts an internally compensated Constant-On-Time (COT) control mode that provides fast transient response and eases loop stabilization. The operating frequency is easily set to 600kHz, 800kHz, or 1000kHz via the MODE pin configuration, allowing the frequency to remain constant across various input and output voltages. The output voltage start-up ramp is controlled by an internal 1ms timer and can be increased by adding a capacitor on the SS pin.

An open-drain Power Good (PGOOD) signal indicates whether the output is within its nominal voltage range. When the input supply fails to power the MP8795, PGOOD is clamped to approximately 0.7V via an external pull-up voltage. Comprehensive protection features include Over-Current Protection (OCP), Over-Voltage Protection (OVP), Under-Voltage Protection (UVP), Under-Voltage Lockout (UVLO), and Thermal Shutdown (OTP). The device requires a minimal number of standard external components and is available in a QFN-21 (3mm × 4mm) package, rated for operation from –40°C to +125°C junction temperature.

15A Output Current Fully integrated synchronous buck converter with low R_DS(ON) power MOSFETs, delivering up to 15A over a wide 4V to 16V input range.

COT Control with Fast Transient Response Internally compensated Constant-On-Time control simplifies loop stabilization and provides fast transient response for demanding load steps.

Programmable Frequency & Current Limit Selectable 600kHz/800kHz/1000kHz switching frequency and programmable accurate current limit level for design flexibility.

DEVICE HIGHLIGHTS

Key Features and Benefits of MP8795GLE-P

Circuit Considerations for MP8795GLE-P

Frequency, Mode & Soft-Start Configuration

The MP8795GLE-P offers flexible configuration via external components:

Switching Frequency (MODE Pin): Configure the MODE pin to select 600kHz, 800kHz, or 1000kHz operation. The frequency remains constant across input and output voltage variations.
Operating Mode: Selectable pulse-skipping mode for high light-load efficiency or forced Continuous Conduction Mode (CCM) for fixed-frequency, low-ripple operation.
Soft-Start (SS Pin): The internal 1ms timer controls the default start-up ramp. Add a capacitor on the SS pin to extend the start-up time and reduce inrush current.
Current Limit: A programmable accurate current limit level allows optimization for the selected inductor and output capacitor.
Output Voltage (FB Pins): Use a resistor divider from V_OUT to the differential FB pins to set the output voltage from 0.6V to 5.5V.

PCB and System-Level Guidance

Buck converter performance depends on layout and component selection:

Input Capacitors: Place high-frequency ceramic decoupling capacitors close to the VIN and PGND pins with wide, short traces to minimize input ripple and parasitic inductance.
Inductor and Output Capacitors: Select based on switching frequency, output current, and ripple requirements. Follow the datasheet recommendations for the chosen operating frequency.
BST Capacitor: Connect a capacitor between the SW and BST pins to form the floating supply for the high-side MOSFET driver.
Differential Remote Sense: Route the differential FB traces as a tight pair from the load point back to the device to accurately compensate for PCB trace and cable drops.
Thermal Management: The QFN-21 package relies on the PCB ground plane and thermal vias for heat dissipation. Solder the exposed pad to a large ground copper area.
Verify the recommended PCB footprint from the official datasheet prior to production.

REPLACEMENT GUIDANCE

Selecting an Alternative for MP8795GLE-P

A replacement for the MP8795GLE-P should not be selected solely by product category.
