Analog Devices Inc./Maxim Integrated MAX1510EVKIT

Overview

The MAX1510EVKIT from Maxim Integrated is a fully assembled and tested evaluation kit designed to demonstrate and validate the MAX1510 low-voltage linear regulator for DDR memory termination applications. It supports 0.5V–1.5V output voltage regulation, sources/sinks up to 1.5A continuously, accepts 1.1V–3.6V input, and features remote sensing, buffered reference output (REFOUT), and open-drain power-good signaling.

For engineers reviewing the MAX1510EVKIT datasheet, MAX1510EVKIT pinout, MAX1510EVKIT application, or MAX1510EVKIT equivalent, key selection considerations include its 10-pin TDFN-eval-board form factor, dual-reference configuration (REF_IN/REFOUT), shutdown control via JU1, output regulation source selection via JU2, and DDR-specific decoupling capacitor simulation (C7–C10).

Technical Context

The MAX1510EVKIT implements the MAX1510 IC in a functional test environment with dedicated bias (3.3V VCC) and main input (1.1V–3.6V IN) rails. Its circuitry includes internal n-channel MOSFETs, a 12kΩ internal OUT-to-OUTS sense resistor, and configurable reference routing through R1/R2 divider network.

Remote sensing is enabled via the OUTS pad directly tied to the MAX1510's OUTS pin, while local sensing is maintained by the internal resistor. REFOUT delivers a buffered copy of REFIN (set to 0.5× REF_IN or 0.5× IN depending on JU2), active when REFIN > 0.45V and VCC > 2.65V, independent of shutdown state.

FAQ

What is the primary function of the MAX1510EVKIT?

The MAX1510EVKIT is an evaluation platform for the MAX1510 low-voltage linear regulator, specifically engineered for DDR memory termination. It enables functional verification of output regulation (0.5V–1.5V), ±1.5A sink/source capability, remote sensing, REFOUT buffering, and PGOOD signaling under real-world DDR load conditions. The MAX1510EVKIT includes all necessary passive components and jumpers for flexible configuration.

How does the MAX1510EVKIT configure its output voltage reference?

The MAX1510EVKIT selects its output voltage reference using jumper JU2: with a shunt installed, REF_IN connects to the IN pad, setting output to 0.5× IN voltage; with no shunt, REF_IN accepts an external reference, setting output to 0.5× that reference. This configuration directly controls the MAX1510's REFIN pin, which the IC uses to regulate the OUTS node - and thus the output voltage - to match REFIN.

What are the power supply requirements for operating the MAX1510EVKIT?

The MAX1510EVKIT requires two independent supplies: a 3.3V, 100mA bias rail (VCC) for MAX1510 internal circuitry and gate drive, and a 1.1V–3.6V, 5A main input rail (IN) for the regulated output stage. Both supplies must share PGND. The VCC rail must exceed 2.65V for REFOUT activation, and REFIN must exceed 0.45V for REFOUT to remain active - even during shutdown.

Does the MAX1510EVKIT support remote voltage sensing, and how is it implemented?

Yes, the MAX1510EVKIT supports remote sensing via the OUTS pad, which is directly connected to the MAX1510's OUTS pin. The MAX1510 regulates the voltage at OUTS to match REFIN. To enable remote sensing at the DDR load, users cut the PCB trace between R4 pads and connect OUTS to the load point. Local sensing remains available via the internal 12kΩ resistor between OUT and OUTS - ensuring regulation continuity if OUTS is disconnected.

What is the role of the PGOOD signal on the MAX1510EVKIT, and how is it interfaced?

The PGOOD signal on the MAX1510EVKIT is an open-drain output from the MAX1510's PGOOD pin, pulled up to 3.3V via resistor R3. It asserts logic-low when the output is out of regulation or during shutdown (JU1 pins 2–3). The PGOOD pad allows direct connection to system monitoring logic. This signal provides real-time status feedback critical for DDR subsystem health checks and power sequencing validation using the MAX1510EVKIT.
