Product details
Overview
ISL6228EVAL3Z from Renesas Electronics is an evaluation board designed to demonstrate the performance of the ISL6228 dual-channel PWM controller with Robust Ripple Regulator (R3) technology. It supports configurable 1.5V/1.8V Channel-1 output and fixed 1.8V Channel-2 output, includes on-board dynamic-load generators (4.5A/300µs for VO1, 5A/300µs for VO2), and operates across 3.3–25V input range - enabling validation of transient response, efficiency, and stability in multi-rail CPU/GPU core power applications.
For engineers reviewing the ISL6228EVAL3Z datasheet, ISL6228EVAL3Z interface connections, ISL6228EVAL3Z test setup, or ISL6228EVAL3Z schematic and BOM, this board provides full access to VIN1/VIN2, VO1/VO2, PHASE1/PHASE2, PGOOD signals, loop gain measurement points (TP5–TP8), and dynamic-load control via S1–S5 switches - supporting comprehensive characterization of dual-phase DC/DC regulation under CCM/DCM and load-step conditions.
Technical Context
The ISL6228EVAL3Z implements the ISL6228HRZ QFN-28 dual-channel synchronous buck controller driving two independent power stages: Channel-1 uses IRF7821PBF and IRF7832PBF MOSFETs with 3.3µH chokes (L1/L2), while Channel-2 employs identical topology with separate gate drivers (HIP2100IBZ). Each channel features dedicated enable (EN1/EN2), feedback (FB1/FB2), overcurrent (OCSET1/OCSET2), and power-good (PGOOD1/PGOOD2) interfaces.
It integrates calibrated dynamic-load circuitry applying precise 300µs current pulses (4.5A on VO1, 5A on VO2) for repeatable transient-response testing, and provides 14 test points (TP1–TP21) covering input/output voltages, phase nodes, enable signals, and loop compensation nodes - enabling direct oscilloscope probing without soldering or signal attenuation.

FAQ
What is the primary function of the ISL6228EVAL3Z evaluation board?
The ISL6228EVAL3Z evaluation board is a fully assembled, tested platform that demonstrates the operation and performance of the ISL6228 dual-channel PWM controller. It enables engineers to validate key parameters including efficiency, startup/shutdown behavior, steady-state regulation in CCM/DCM modes, and load-transient response - using built-in dynamic-load generators and comprehensive signal access points. The ISL6228EVAL3Z does not operate as a standalone power supply but serves exclusively as a characterization tool for the ISL6228HRZ controller.
Which controller IC does the ISL6228EVAL3Z evaluate, and what package is used?
The ISL6228EVAL3Z evaluates the ISL6228HRZ - a 28-pin QFN-packaged dual-channel synchronous buck PWM controller featuring Intersil's Robust Ripple Regulator (R3) technology. The ISL6228HRZ is mounted directly on the board and interfaces with discrete MOSFETs, gate drivers (HIP2100IBZ), and passive components to form two complete power stages. No other controller variants or packages are supported on this board.
How are the output voltages configured on the ISL6228EVAL3Z?
Channel-1 output voltage on the ISL6228EVAL3Z is user-selectable between 1.5V and 1.8V using switch S5, which parallels resistor R49 with R15 to adjust the FB1 divider ratio. Channel-2 output is fixed at 1.8V via R20/R23 feedback network. Both outputs are accessible at screw terminals (J7–J10) and test points (TP11–TP14), with independent enable controls (S1 for Channel-1, S2 for Channel-2).
What power supplies are required to operate the ISL6228EVAL3Z?
The ISL6228EVAL3Z requires three independent DC power sources: two adjustable 25V/3A supplies for VIN1 (J14) and VIN2 (J1/J2), one fixed 5V/100mA supply for VCC (TP1/TP2), and one fixed 12V/100mA supply for the dynamic-load generator (TP15/TP16). Input voltage ranges must stay within 3.3–25V for VIN1/VIN2 to ensure proper ISL6228HRZ operation and avoid damage to onboard components.
Does the ISL6228EVAL3Z include provisions for loop stability analysis?
Yes, the ISL6228EVAL3Z provides dedicated loop gain measurement nodes: TP5 and TP6 are the common nodes of R24/R20 and R25/R23 respectively; TP7 and TP8 connect to the VO1 and VO2 sides of those same resistors. These points allow injection of AC signals and measurement of open-loop gain/phase margins using a network analyzer - enabling direct verification of compensation network stability per the ISL6228HRZ application guidelines.
