Product details
Overview
ISLACDC750WEVKIT1Z from Renesas is a complete evaluation kit comprising a motherboard (ISLACDC750W-MBEV1Z) and three daughter boards (ISL6731x-DB-1Z, ISL6721-DB-1Z, ISL6754DBEVAL2Z) implementing an active PFC stage and asymmetrical full-bridge ZVS DC/DC converter for ATX PC power supplies. It delivers 12V at 62.5A (750W) from 90–264VAC input, achieves >80% efficiency, and integrates comprehensive protection including OVP, UVP, OCP, OTP, and short-circuit.
For engineers reviewing the ISLACDC750WEVKIT1Z datasheet, ISLACDC750WEVKIT1Z pinout, ISLACDC750WEVKIT1Z application, or ISLACDC750WEVKIT1Z equivalent, this kit supports rapid validation of high-efficiency, high-current AC/DC conversion topologies with adaptive THD/PF optimization, remote control via PS-ON#, and Power-Good signaling - critical for server PSU, industrial power module, and battery charger reference design.
Technical Context
The ISLACDC750WEVKIT1Z implements a two-stage architecture: a boost PFC controller (ISL6731) operating in CCM with adaptive line/load compensation (Sp/Sv signals), and an asymmetrical full-bridge ZVS DC/DC converter (ISL6754 + ISL6721) delivering regulated 12V output. The PFC stage uses voltage-mode control with BO and COMP pins to dynamically adjust current loop gain and sense gain for improved THD across line/load conditions.
Protection is implemented at both stages: PFC OVP/UVP via ISL6731's BO pin and DC/DC OCP/OVP/OTP via ISL6754's fault comparators and ISL6144 ORing controller. The kit supports current sharing (iShare bus), hot-swap ORing, and standby mode that disables PFC and DC/DC to reduce no-load loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 90–264VAC universal input; enables single design for global mains compliance without manual voltage selection. |
| Output Voltage | 12VDC ±1.5% regulation; meets ATX specification for main rail and supports high-current CPU/GPU loads. |
| Maximum Output Power | 750W continuous; defined by FETs (FCP22N60N, IPB100N10S3-05), transformer (Wurth 750342506), and thermal design. |
| Peak Efficiency | >80% at 230VAC/50Hz full load; achieved via ZVS operation, low-Rds(on) MOSFETs, and optimized magnetics. |
| Power Factor | >0.95 at full load (230VAC); maintained above 0.90 down to 20% load using adaptive Sp/Sv gain control. |
| THD | <15% at full load (230VAC); reduced to <8% at light load via dynamic crossover frequency adjustment. |
| Protections | Input OVP/UVP, output OVP/OCP (constant-current limit), OTP, short-circuit, and PG signaling - ensures robust field reliability. |

FAQ
What is the primary function of the ISLACDC750WEVKIT1Z?
The ISLACDC750WEVKIT1Z is a complete evaluation kit for a 750W active PFC + asymmetrical full-bridge ZVS converter targeting ATX PC power supplies. It integrates Renesas ISL6731, ISL6721, and ISL6754 controllers on dedicated daughter boards, plus a motherboard with power stage components, enabling immediate hardware validation of high-efficiency AC/DC conversion. The ISLACDC750WEVKIT1Z supports full-feature testing including adaptive THD reduction, current sharing, and remote ON/OFF control.
Can the ISLACDC750WEVKIT1Z be used for battery charger applications?
Yes - the ISLACDC750WEVKIT1Z can be adapted to off-line battery chargers. The I_LIM and V_CTRL analog inputs on the ISL6754DBEVAL2Z board allow MCU-based programming of charge current and floating voltage. Transformer T3 and inductor L5 may require redesign for different output voltage/current profiles, and ORing/FET current-sharing circuitry can be removed for standalone operation. The ISLACDC750WEVKIT1Z documentation explicitly confirms this adaptation path.
What are the key interface signals on the ISLACDC750WEVKIT1Z motherboard?
The ISLACDC750WEVKIT1Z motherboard provides standardized ATX-compatible signals: PS-ON# (active-low logic input for remote power enable), PG (Power-Good open-drain output indicating stable 12V), iShare (analog current-sharing bus), SYNC (external synchronization input), and analog inputs I_LIM and V_CTRL for charger configuration. These interfaces are documented in Table 3 of UG043 and physically accessible via J1 (16-pin header) and J9 (6-pin header).
Does the ISLACDC750WEVKIT1Z include thermal management provisions?
Yes - the ISLACDC750WEVKIT1Z requires forced air cooling for long-term operation, especially at low-line (90–115VAC) full load. The user manual specifies "a fan is required" and includes thermal sensing (NTC RT1) and overtemperature protection (OTP) triggered via comparator U24B. Heat sinks are mounted on high-power FETs (Q7–Q15, Q701), and PCB layout incorporates thermal vias and copper pours per Renesas thermal guidelines for the ISL6754 and ISL6721 controllers.
How does the ISLACDC750WEVKIT1Z achieve low THD across varying line and load conditions?
The ISLACDC750WEVKIT1Z uses analog adaptive control: the ISL6731's Sp signal (load-dependent) and Sv signal (line-dependent) dynamically adjust current-loop gain and current-sense gain via external FET switches (Q3–Q6) and resistor networks. This pushes crossover frequency higher under light-load or high-line conditions - where DCM operation makes the loop inherently stable - improving THD without DSP complexity. This behavior is verified in Figures 6 and 7 of UG043.
