Product details

Overview

ISL8104EVAL2Z from Renesas Electronics is a fully assembled, tested evaluation board for the ISL8104 single-phase synchronous buck PWM controller. It implements a 1.8V/20A DC/DC converter using voltage-mode control, 300kHz switching frequency, r_DS(ON)-based overcurrent protection, and pre-bias soft-start-designed for power supply validation in industrial and embedded systems.

For engineers reviewing the ISL8104EVAL2Z datasheet, ISL8104EVAL2Z pinout, ISL8104EVAL2Z application, or ISL8104EVAL2Z equivalent, this board enables rapid characterization of transient response (0–20A step), efficiency (peak >90% at 12V input), output ripple (<30mV_P-P), OCP threshold (~25A), and loop stability with Type-III compensation.

Technical Context

The ISL8104EVAL2Z implements a complete single-phase synchronous buck topology with integrated high- and low-side MOSFET drivers. It uses the ISL8104IRZ controller in a 16-pin 4×4 MLFP package, configured for 1.8V output via resistor-divider feedback (R1=23.2kΩ, R4=11.5kΩ) and Type-III compensation (C1=2.2nF, C2=82pF, R3=665Ω, C3=1.5nF).

Power stage components include Vishay IHLP5050FD-R68 (0.68µH, 1.6mΩ DCR) inductor, four Fujitsu FP-4R0RE561M-L8 polymer capacitors (4×560µF, <4mΩ ESR), three Sanyo 35ME330AX bulk input caps (3×330µF), and Infineon BSC080N03LS (high-side) + dual BSC030N03LS (low-side) MOSFETs-optimized for conduction and switching loss balance at 20A continuous load.

Key Specifications

Parameter	Value and Actual Design Meaning

FAQ

What is the primary function of the ISL8104EVAL2Z?

The ISL8104EVAL2Z is a ready-to-use evaluation board that demonstrates the ISL8104IRZ synchronous buck PWM controller in a complete 1.8V/20A power supply. It enables engineers to validate transient response, efficiency, loop stability, and protection features without designing a custom PCB. The ISL8104EVAL2Z includes all critical power stage components, test points, and jumper-configurable bias options for rapid lab testing.

How does the ISL8104EVAL2Z differ from the ISL8104EVAL1Z?

The ISL8104EVAL2Z uses the ISL8104IRZ controller in a 16-pin 4×4 MLFP package (vs. ISL8104IBZ in 14-pin SOIC on EVAL1Z), adding SS_DONE and REFIN pins for enhanced start-up monitoring and external reference injection. It also includes an additional green LED (D2) and expanded test point count (TP1–TP10), while retaining identical power stage design, component selection, and performance specifications.

Can the ISL8104EVAL2Z be used to evaluate other output voltages?

Yes-the ISL8104EVAL2Z supports reconfiguration for different output voltages by modifying the FB resistor divider (R1 and R4). The board's schematic and AN1416 provide equations and layout guidance for adjusting R4 to target voltages such as 1.2V or 3.3V, while maintaining loop compensation integrity through recalculated Type-III network values (R2, C1–C3).

What input voltage range is supported by the ISL8104EVAL2Z?

The ISL8104EVAL2Z operates with an input voltage range of 8V to 14.4V, matching the ISL8104IRZ controller's specified bias supply requirements. It accepts single-rail input via terminals J1/J2, with optional separate bias supply routing through J6-enabling flexible testing under nominal 12V, automotive battery (9–16V), or industrial 10–14V conditions.

Does the ISL8104EVAL2Z include overcurrent protection, and how is it implemented?

Yes-the ISL8104EVAL2Z implements r_DS(ON)-based overcurrent protection using the top-side MOSFET's on-resistance, eliminating the need for a sense resistor. With RTSOC = 1.15kΩ and BSC080N03LS, the trip point is set to ~25A. The design includes 120ns blanking and parallel RC filtering (RTSOC/CTSOC) to reject switching noise, ensuring reliable fault detection during fast transients.
