Product details
Overview
The ISL81801DEMO1Z from Renesas Electronics is a demonstration board for the ISL81801 80V high-voltage synchronous buck-boost controller, featuring bidirectional operation, programmable 200kHz switching frequency, 48V/10A regulated output, and integrated UV/OV/OC/OT protection. It enables rapid evaluation of high-efficiency, high-current DC/DC conversion in industrial power systems and energy storage interfaces.
For engineers reviewing the ISL81801DEMO1Z datasheet, ISL81801DEMO1Z pinout, ISL81801DEMO1Z application, or ISL81801DEMO1Z equivalent, this board provides validated reference design, parallelable architecture, jumper-configurable DEM/PWM and CC/HICCUP OCP modes, and full test point access to critical IC signals including PHASE, FB, EN, and PGOOD.
Technical Context
The ISL81801DEMO1Z implements the ISL81801 TQFN-32 controller in a complete, pre-layout-optimized 4-switch buck-boost topology. It supports input voltages from 32V to 80V and delivers a stable 48V output at up to 10A continuous load, with OCP set at minimum 11A at room temperature.
Key operational features include jumper-selectable forced PWM or pulse-skipping DEM mode, constant-current or hiccup overcurrent protection, prebias soft-start capability, and daisy-chain parallel operation with phase-shift control via J6/J7 jumpers - enabling scalable high-power solutions without redesign.
Key Specifications

FAQ
What is the primary function of the ISL81801DEMO1Z?
The ISL81801DEMO1Z is a fully assembled demonstration board that showcases the ISL81801 80V synchronous 4-switch buck-boost controller. It provides immediate hands-on evaluation of bidirectional power flow, programmable protection, parallel operation, and efficiency optimization - all using the exact ISL81801FRTZ IC in its intended application context.
Can the ISL81801DEMO1Z operate in bidirectional mode?
Yes, the ISL81801DEMO1Z supports verified bidirectional operation. As documented in Section 1.4 of its user manual, floating the FBI pin and configuring for PWM mode enables controlled charging of supercapacitors or batteries from the 48V output rail - with input voltage required above 36V during initial charge and VIN limit disabled via jumper J7.
How is output current limiting configured on the ISL81801DEMO1Z?
Output current limiting on the ISL81801DEMO1Z is selected via jumper J9: shorting Pins 1–2 configures constant-current (CC) OCP, while shorting Pins 2–3 enables hiccup-mode (HICCUP) OCP. The default OCP threshold is set to ≥11A at room temperature using onboard sense resistors, aligning with the 10A rated output current.
Does the ISL81801DEMO1Z support parallel operation?
Yes, the ISL81801DEMO1Z is explicitly designed for parallel operation in daisy-chain configurations. Figures 2 and 3 in the user manual show wiring for two and three units, with phase shift controlled via jumpers J6 and J7 - enabling interleaved operation to reduce input/output ripple and scale total output current beyond 10A.
What are the key layout features of the ISL81801DEMO1Z PCB?
The ISL81801DEMO1Z uses a 4-layer PCB with dedicated power and signal ground planes (Layers 2 & 3), minimized high-current loops for buck/boost phases, short gate-drive traces, and isolated analog feedback routing. Its layout follows Renesas' strict guidelines - including separate SGND/PGND connection near the IC and optimized placement of input/output capacitors and MOSFETs - to ensure reliable high-frequency, high-current operation.
