Product details
Overview
ISL78236DUALEVAL1Z from Renesas Electronics is a dual-output evaluation board designed to demonstrate the ISL78236 dual 3A synchronous buck regulator in Point-of-Load (POL) applications with input voltage range 2.85V–6V, delivering up to 3A per channel at 1.8V output, and supporting current-share mode for 6A single output.
For engineers reviewing the ISL78236DUALEVAL1Z datasheet, ISL78236DUALEVAL1Z setup procedure, ISL78236DUALEVAL1Z output voltage adjustment, or ISL78236DUALEVAL1Z synchronization configuration, this board enables rapid validation of efficiency, transient response, phase interleaving, and soft-start behavior under real POL conditions with minimal external equipment.
Technical Context
The ISL78236DUALEVAL1Z implements the ISL78236IRZ controller in a fully assembled, tested layout with 4mm×4mm QFN-24 footprint, configured for 1.8V/1.8V dual outputs using 100kΩ feedback resistors (RF11/RF21) and 124kΩ programming resistors (RF12/RF22). It supports internal 2.5MHz switching or external SYNC input from 6MHz–8MHz for out-of-phase channel operation.
Key operational features include 180° phase-shifted PWM, internal digital soft-start (1.5ms), soft-stop discharge, 8µA shutdown current, and protection mechanisms including peak current limiting, hiccup-mode short-circuit response, over-temperature shutdown, and negative current detection - all validated on this board via test points and jumper-controlled enable/disable logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Board Type | Evaluation board for ISL78236 dual 3A buck regulator - not a standalone IC or discrete component. |
| Input Voltage Range | 2.85V to 6V - supports automotive and industrial POL rails including 3.3V, 5V, and battery-sourced supplies. |
| Output Configuration | Dual independent 3A channels (VOUT1/VOUT2), preset to 1.8V; adjustable from 1.2V to 3.3V via feedback resistor selection. |
| Switching Frequency | 2.5MHz (internal default) or externally synchronized from 6MHz to 8MHz - enables phase interleaving and EMI reduction. |
| Control Interface | PWM/EN control via S1/S2/S3 toggle switches; SYNC pin accessible via test point for external clock injection. |
| Protection Features Verified | Over-temperature shutdown, hiccup-mode short-circuit protection, negative current detection, and soft-stop discharge - all observable during functional testing. |

FAQ
What is the primary function of the ISL78236DUALEVAL1Z?
The ISL78236DUALEVAL1Z is an evaluation board used to characterize and validate the ISL78236 dual 3A synchronous buck regulator. It provides a ready-to-use hardware platform with pre-populated components, test points, and switch-controlled operation to evaluate efficiency, transient response, phase interleaving, and protection features under real-world POL conditions.
Can the ISL78236DUALEVAL1Z be used for output voltages other than 1.8V?
Yes - the ISL78236DUALEVAL1Z supports adjustable output voltages from 1.2V to 3.3V per channel by replacing RF12 (for VOUT1) and RF22 (for VOUT2) with values calculated using Equations 1 and 2 in AN1927. The board ships with 124kΩ resistors set for 1.8V, but resistor pads are accessible for rework.
How does the SYNC feature work on the ISL78236DUALEVAL1Z?
The ISL78236DUALEVAL1Z exposes the SYNC pin via a dedicated test point adjacent to C_PH. When driven by an external 6MHz–8MHz signal (negative-edge triggered), it forces both channels to operate at half that frequency with 180° phase shift. Leaving the pin floating defaults to internal 2.5MHz operation; tying it low is prohibited.
What power supply requirements are needed to operate the ISL78236DUALEVAL1Z?
A minimum 5V supply capable of delivering ≥6A is required to fully load both channels at 3A each. The board accepts input across VIN1 and VIN2 terminals with common PGND return. Battery sources (e.g., 5V LiPo) are also supported, provided current and stability meet ISL78236's input ripple and dropout specifications.
Does the ISL78236DUALEVAL1Z support current-sharing mode for 6A output?
No - the ISL78236DUALEVAL1Z is configured for independent dual 3A operation. To evaluate 6A current-share mode, Renesas specifies the separate ISL78236CRSHEVAL1Z evaluation board (AN1928), which uses different layout and component selection to enable master-slave interleaving and shared current sensing.
