Monolithic Power Systems Inc. EV5030-QH-00C

Overview

EV5030-QH-00C from Monolithic Power Systems is a USB charging evaluation board centered on the MP5030GQH IC, a USB Type-C 5V/3A DFP port controller with integrated current-limit switch and QC 3.0 (3.6–12V) voltage negotiation capability. It supports BC1.2 DCP modes (Divider, 1.2V/1.2V), features 32mΩ R_DS(ON), hiccup current limiting, input OVP up to 36V, and linear line-drop compensation for stable 5.15V output under load.

For engineers reviewing the EV5030-QH-00C datasheet, EV5030-QH-00C pinout, EV5030-QH-00C application, or EV5030-QH-00C equivalent, this board enables rapid validation of MP5030-based USB PD-adjacent 5V/3A Type-C and QC3.0 charging designs - especially for wall adapters, automotive cigarette-lighter supplies, and multi-port power banks requiring accurate VBUS control and mode transition timing.

Technical Context

The EV5030-QH-00C implements a complete reference design for MP5030GQH in QFN-10 (1.5mm×2mm) package, integrating a synchronous buck converter (MP2499M) to generate VCC1/VCC2 rails, discrete USB-A and USB-C connectors, and resistor-programmable ILIM via R8 (1.4kΩ). CC1 pull-down configuration (R10 = 5.1kΩ) enables Type-C DFP 5V@3A mode; removal of R10 activates QC3.0 negotiation.

Board-level signal routing isolates DP/DM lines for BC1.2 detection, routes BST/SW/PGND for optimal switching loop integrity, and places ceramic (22µF ×4) and bulk (100µF) output capacitance adjacent to MP5030's VOUT pin. Thermal relief for U2 (MP5030) uses exposed thermal pad connected to internal GND plane.

FAQ

What is the purpose of R10 (5.1kΩ) on the EV5030-QH-00C board?

R10 pulls down CC1 to enable USB Type-C Downstream Facing Port (DFP) 5V@3A mode. Removing R10 disables CC1 pull-down and allows MP5030 to enter QC3.0 negotiation using D+/D− signaling - a hardware-selectable mode toggle confirmed in the Quick Start Guide and test results.

Can both USB-A and USB-C ports operate simultaneously on this board?

No. The EV5030-QH-00C design explicitly states that Type-A and Type-C ports cannot be used at the same time. This is enforced by shared VOUT routing and single MP5030 IC resource allocation - only one port may be active during testing per the user guide.

What input voltage should be applied during evaluation?

A preset 14V DC input is specified in the Quick Start Guide. This aligns with MP5030's 9–16V operating range and ensures sufficient headroom for line-drop compensation while staying within the 36V absolute maximum rating.

Does the board include a full USB Power Delivery (USB-PD) implementation?

No. EV5030-QH-00C supports USB Type-C 5V@3A DFP mode and QC3.0 (3.6–12V), but not full USB-PD 2.0/3.0 with variable voltage up to 20V or bidirectional communication. It implements BC1.2 and Qualcomm proprietary protocols only - no BMC signaling or PD controller IC is present.

How is thermal performance validated on this evaluation board?

Thermal shutdown behavior is verified in test results (page 4), showing recovery after fault clearance. The MP5030's exposed thermal pad is soldered to the board's internal GND plane, and layout figures confirm copper pour under U2 - consistent with QFN-10 thermal guidelines in MP5030's datasheet.
