Product details
Overview
ISL8036DUALEVAL1Z from Renesas Electronics is a dual-channel 3A synchronous buck regulator evaluation kit designed to demonstrate the ISL8036IRZ IC in point-of-load applications with 2.85V–6V input and preset 1.8V outputs. It supports external synchronization up to 6MHz, features 180° out-of-phase operation, and delivers up to 95% efficiency in a compact 4mm×4mm QFN footprint.
For engineers reviewing the ISL8036DUALEVAL1Z datasheet, ISL8036DUALEVAL1Z pinout, ISL8036DUALEVAL1Z application, or ISL8036DUALEVAL1Z equivalent, this board enables rapid validation of dual-output DC/DC regulation, soft-start behavior, power-good sequencing, and load-transient response under real-world PoL conditions.
Technical Context
The ISL8036DUALEVAL1Z implements two independent ISL8036IRZ buck regulators operating in current-mode control with internal compensation. Each channel supports 0.8V–3.3V adjustable output via external feedback resistors (RF11/RF12, RF21/RF22), and features dedicated EN1/EN2, PG1/PG2, and SYNC pins for coordinated power sequencing and synchronization.
It integrates 1.5ms digital soft-start, 1ms-delayed power-good signals, hiccup-mode short-circuit protection, and negative current detection. The board uses 1.5µH shielded power inductors (L1/L2), 22µF input/output ceramic capacitors, and 124kΩ preset feedback resistors to achieve 1.8V outputs with ±2% accuracy over line, load, and temperature.

FAQ
What is the primary function of the ISL8036DUALEVAL1Z?
The ISL8036DUALEVAL1Z is an evaluation kit for the ISL8036IRZ dual 3A synchronous buck regulator. Its purpose is to demonstrate and validate the performance of the ISL8036IRZ IC in real-world point-of-load applications, including efficiency measurement, transient response, power sequencing, and output voltage adjustability. The ISL8036DUALEVAL1Z provides pre-populated circuitry, test points, and configuration jumpers to simplify lab characterization without custom PCB design.
Can the output voltages of the ISL8036DUALEVAL1Z be adjusted, and how?
Yes, the ISL8036DUALEVAL1Z supports output voltage adjustment from 0.8V to 3.3V per channel using external feedback resistors RF11/RF12 (Channel 1) and RF21/RF22 (Channel 2). With RF11 and RF21 fixed at 100kΩ, changing RF12 and RF22 sets the output per Equation 1 and Equation 2 in the user manual. For example, replacing the default 124kΩ RF12/RF22 with 0Ω shorts yields 0.8V output. A 47pF capacitor may be added in parallel for improved transient response.
Does the ISL8036DUALEVAL1Z support external clock synchronization?
Yes, the ISL8036DUALEVAL1Z supports external synchronization up to 6MHz via the SYNC pin on the ISL8036IRZ IC. The SYNC signal must be applied as a negative-edge-triggered logic input - it must never be left floating or tied low. The board includes a dedicated test point (SYNC) and routing to accept an external function generator, enabling precise phase alignment or EMI spread-spectrum control across multiple converters.
What protections are implemented on the ISL8036DUALEVAL1Z?
The ISL8036DUALEVAL1Z inherits all protections of the ISL8036IRZ IC: peak current limiting, hiccup-mode short-circuit protection, over-temperature shutdown, and negative current detection. These are active during operation and verified on the board layout through proper thermal pad grounding (EP), current-sense resistor placement, and thermal vias. No additional external components are required to enable these protections on the ISL8036DUALEVAL1Z.
Is the ISL8036DUALEVAL1Z compatible with other ISL80xx evaluation boards?
The ISL8036DUALEVAL1Z shares mechanical and layout conventions with the ISL8033_36EVAL1ZREVA PCB platform, including identical mounting holes, test point locations, and connector footprints. However, it is not electrically interchangeable with single-channel variants like ISL8033EVAL1Z due to differences in IC pinout, feedback network, and dual-channel control logic. Users should consult AN1617 Rev 0.00 for exact jumper and configuration requirements specific to the ISL8036DUALEVAL1Z.
