Renesas ISL8206MEVAL1Z

Overview

ISL8206MEVAL1Z from Renesas Electronics is an evaluation board designed to characterize the ISL8206M point-of-load (POL) DC/DC power module - a 6A, 0.6V–6V output, wide-input (1V–20V) synchronous buck regulator with integrated MOSFETs and compensation. It supports quick-start evaluation using +5V or +12V input without external PVCC bias, and enables precise VOUT adjustment via R1 (e.g., 6.49kΩ for 1.5V), current limit tuning via R4 (4.12kΩ), and efficiency/ripple/noise measurement per AN1386.

For engineers reviewing the ISL8206MEVAL1Z datasheet, ISL8206MEVAL1Z pinout, ISL8206MEVAL1Z application, or ISL8206MEVAL1Z equivalent, this board delivers validated test infrastructure for evaluating ISL8206M performance across input voltage extremes (1V–20V), load conditions up to 6A, output ripple under real PCB layout, and thermal behavior in POL-constrained environments.

Technical Context

The ISL8206MEVAL1Z implements a fixed-frequency synchronous buck topology with internal high- and low-side MOSFETs, type-3 compensation network, and integrated current-sense resistor (RSEN-IN = 4.12kΩ). It supports programmable overcurrent protection and uses external feedback resistors (R1, R2, R3) to set output voltage from 0.6V to 6V.

Board-level features include dual PVCC bias selection (VIN-derived or external +5V/+12V/+6.5V–+14.4V), hardware enable/disable via S2 switch on COMP/EN, snubber network (R18/C18/C19), and dedicated measurement points (C3 for VIN, C8 for VOUT) to minimize probe-induced noise during efficiency and ripple testing.

FAQ

What is the primary function of the ISL8206MEVAL1Z?

The ISL8206MEVAL1Z is a dedicated evaluation board for the ISL8206M point-of-load DC/DC module. It provides a complete, tested hardware environment to measure efficiency, output ripple/noise, transient response, and thermal performance of the ISL8206M under real-world conditions - including wide input range (1V–20V), adjustable output (0.6V–6V), and up to 6A load. The ISL8206MEVAL1Z includes all necessary passive components, biasing switches, and calibrated test points per AN1386.

How do I configure the ISL8206MEVAL1Z for 1.5V output?

To configure the ISL8206MEVAL1Z for 1.5V output, install a 6.49kΩ resistor at R1 position (per Table 3 and Figure 8 in AN1386). R2 and R3 are optional parallel resistors for fine-tuning. Ensure S1 is set to "UP" if using +5V or +12V input (enabling VIN-derived PVCC), and S2 is "UP" to enable the ISL8206M via COMP/EN. The ISL8206MEVAL1Z ships with R1 pre-populated at 6.49kΩ for default 1.5V operation.

Does the ISL8206MEVAL1Z require an external PVCC supply?

No - the ISL8206MEVAL1Z does not require an external PVCC supply when input voltage is +5V or +12V. In those cases, switch S1 is set to "UP" to route VIN directly to the PVCC pin of the ISL8206M. For input voltages outside +5V/+12V (e.g., 1V–4.9V or 14.1V–20V), an external PVCC source (+5V ±10%, +12V ±20%, or +6.5V–+14.4V) must be connected with S1 set to "DOWN". This behavior is explicitly defined in AN1386 Section "Installation" and Table 2.

What test equipment is recommended for evaluating the ISL8206MEVAL1Z?

AN1386 specifies a GW GPC–3060D DC power supply (30V/15A), Chroma 63030/63010 electronic load (20A sink), Tektronix TDS3014 oscilloscope with P3010 probes, and ESCORT 3136A precision DVM/DCA for voltage/current measurements. Critical measurement points are C3 (input) and C8 (output) - placed to minimize PCB trace impedance and ensure accuracy. The ISL8206MEVAL1Z's layout and test methodology are optimized for use with this equipment set.

Can the ISL8206MEVAL1Z be used to evaluate other ISL820xM modules?

Yes - the ISL8206MEVAL1Z shares identical mechanical and electrical architecture with the ISL8201MEVAL1Z and ISL8204MEVAL1Z boards. Per AN1386 Section "General Description", they are pin-for-pin compatible evaluation platforms differing only in the installed POL module (ISL8201M, ISL8204M, or ISL8206M) and corresponding current-sense resistor (R4 = 3.57kΩ, 2.87kΩ, or 4.12kΩ). Swapping the U1 module and adjusting R4 allows direct comparison of ISL8201M (10A), ISL8204M (4A), and ISL8206M (6A) performance on the same board.
