Product details
Overview
ISL85413EVAL1Z from Renesas Electronics is an evaluation board designed to demonstrate the ISL85413 wide-input synchronous buck regulator (300mA output, 3.3V fixed, 700kHz switching) in point-of-load applications with 3.5V–40V input range and -40°C to +125°C operating junction temperature.
For engineers reviewing the ISL85413EVAL1Z datasheet, ISL85413EVAL1Z pinout, ISL85413EVAL1Z application, or ISL85413EVAL1Z equivalent, this board enables rapid validation of low-quiescent-current buck regulation, PFM/PWM mode selection, and adjustable output voltage (0.6V–12V) using external feedback resistors.
Technical Context
The ISL85413EVAL1Z implements a complete functional test platform for the ISL85413 IC, featuring on-board S1 enable/disable toggle and S2 MODE selector (PFM vs forced PWM), with default PWM configuration via R6=200kΩ to VCC. It integrates all critical passive components-including 33µH power inductor (DR73-330-R), input/output capacitors (10µF/150µF/22µF), and precision feedback network (R1=90.9kΩ, R2=20.0kΩ for 3.3V).
Designed for direct connection to 0–50V/2A bias supplies and electronic loads up to 1.5A, the board supports oscilloscope probing via Tektronix 131-4353-00 test points and includes dual ground planes (GND1/GND2), thermal relief pads, and silk-screened layer diagrams per AN1929 Rev 1.00.
Key Specifications

FAQ
What is the primary function of the ISL85413EVAL1Z?
The ISL85413EVAL1Z is a dedicated evaluation board for the ISL85413 synchronous buck regulator IC. It provides a fully assembled, tested platform to validate performance-including efficiency, transient response, and mode behavior-under real-world input conditions (3.5V–40V), with factory-configured 3.3V/300mA output. The ISL85413EVAL1Z is not a production power module but a design aid for engineers evaluating the ISL85413FRZ IC.
Does the ISL85413EVAL1Z support adjustable output voltage?
Yes, the ISL85413EVAL1Z supports output voltage adjustment from 0.6V to 12V by replacing feedback resistors R1 and R2 per Equation 1 in AN1929. The default 3.3V setting uses R1 = 90.9kΩ and R2 = 20.0kΩ. Table 1 in the user manual lists exact resistor values for common outputs (1.0V–12V), enabling precise reconfiguration without PCB redesign.
How do I configure PFM vs forced PWM mode on the ISL85413EVAL1Z?
Mode selection is controlled by the S2 toggle switch. With S2 in the "PFM" position, the MODE pin is tied to GND, enabling automatic pulse-frequency modulation for light-load efficiency. In the "PWM" position, MODE connects to VCC (via R6 = 200kΩ), forcing continuous conduction mode. This hardware-level control allows immediate comparison of efficiency curves and ripple behavior between modes on the ISL85413EVAL1Z.
What test equipment is required to operate the ISL85413EVAL1Z?
A 0–50V/2A DC power supply, electronic load capable of sinking up to 1.5A, 100MHz quad-trace oscilloscope, digital multimeters, and signal generator are recommended per AN1929. Test points (JLX, JVO) and turret terminals (VIN, VO, GND1/GND2) provide direct access for probing, while mini test points (EN, PG, VCC) support logic-level monitoring of control signals on the ISL85413EVAL1Z.
Is the ISL85413EVAL1Z compatible with the ISL85412 regulator?
No - the ISL85413EVAL1Z is specifically optimized for the ISL85413 (300mA output), with component values (e.g., L1 = 33µH, C3 = 150µF) selected for its higher current capability. The ISL85412EVAL1Z uses different passives (e.g., 150mA-rated inductor/capacitors) and is a separate board. Swapping ICs without verifying loop stability, thermal margin, and current-sense limits is not supported on the ISL85413EVAL1Z.
