Product details
Overview
ISL85413DEMO1Z from Renesas Electronics is a demonstration board for the ISL85413 wide-input synchronous buck regulator, delivering up to 300mA continuous output current with preset 3.3V output, 3.5V–40V input range, and integrated high-side/low-side NMOS FETs. It supports PFM/PWM mode selection and features power-good and enable functions for point-of-load DC/DC conversion in industrial and embedded power systems.
For engineers reviewing the ISL85413DEMO1Z datasheet, ISL85413DEMO1Z pinout, ISL85413DEMO1Z application, or ISL85413DEMO1Z equivalent, this board enables rapid evaluation of transient response, efficiency, light-load behavior, and output voltage adjustability (0.6V–15V) under real-world load and supply conditions.
Technical Context
The ISL85413DEMO1Z implements the ISL85413 IC in a fixed-output configuration using external feedback resistors and includes all necessary passive components-33µH inductor, 22µF output capacitor, 10µF input capacitors, and 1µF bootstrap capacitor-to demonstrate full operation without additional parts. The board uses a 3mm×3mm 8-lead DFN package footprint matching the ISL85413's thermal and electrical layout requirements.
It provides accessible test points (VIN, VOUT, EN, MODE, PG), jumper-selectable mode control (PWM vs. PFM), and on-board soft-start via internal circuitry. Output voltage adjustment requires modifying R1/R2 feedback network per ISL85413 datasheet equations, with default setting yielding 3.3V ±1% at 300mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 300mA continuous - supports stable regulation under sustained load in space-constrained PoL applications. |
| Input Voltage Range | 3.5V to 40V - enables direct connection to unregulated industrial rails, automotive batteries, or telecom supplies without pre-regulation. |
| Default Output Voltage | 3.3V ±1% - factory-preset for immediate testing with common logic and MCU power domains. |
| Adjustable Output Range | 0.6V to 15V - achieved by changing feedback resistor divider; supports custom voltage rails without redesigning board layout. |
| Operating Modes | Selectable PWM or PFM - allows trade-off between light-load efficiency (PFM) and output ripple/noise (PWM). |
| Power-Good Signal | Active-high PG output - provides system-level sequencing and fault monitoring capability for host controllers. |
| Enable Function | EN pin tied to VCC via R7 - ensures default-on operation; removable for external control via 0Ω jumper at R8. |

FAQ
What is the primary function of the ISL85413DEMO1Z?
The ISL85413DEMO1Z is a fully assembled demonstration board for evaluating the ISL85413 synchronous buck regulator. It delivers 3.3V at up to 300mA from a 3.5V–40V input, includes all required passives and test points, and supports mode selection, enable control, and output voltage adjustment - enabling rapid validation of power stage performance without design effort.
Can the output voltage of the ISL85413DEMO1Z be changed from 3.3V?
Yes, the ISL85413DEMO1Z output voltage is adjustable from 0.6V to 15V by modifying the R1/R2 feedback resistor network per the ISL85413 datasheet. Default 3.3V is set by 90.9kΩ (R1) and 20kΩ (R2); replacement resistors must maintain proper divider ratio and stability margins as specified in AN1929 and the ISL85413 datasheet.
How do I switch the ISL85413DEMO1Z between PWM and PFM modes?
The ISL85413DEMO1Z uses R6 (200kΩ to VCC) to default to forced PWM mode. To enable PFM mode, remove R6 and connect the MODE pin directly to GND using a 0Ω resistor or jumper. This change alters light-load efficiency and output ripple characteristics per the ISL85413's internal control logic.
Does the ISL85413DEMO1Z include an enable function, and how is it controlled?
Yes, the ISL85413DEMO1Z includes an enable function. By default, R7 ties the EN pin to VCC for always-on operation. To enable external control, remove R7 and populate R8 with a 0Ω resistor, allowing a logic-level signal to drive the EN pin - supporting power sequencing and standby mode integration in multi-rail systems.
What test equipment is recommended for evaluating the ISL85413DEMO1Z?
Renesas recommends a 0–50V/2A power supply, electronic load capable of sinking up to 1.5A, digital multimeters, a 100MHz quad-trace oscilloscope, and a signal generator. These tools allow measurement of line/load regulation, transient response, efficiency curves, ripple/noise, and mode-switching behavior per AN1931 test procedures.
