Product details

Overview

The ISL78219EV1Z from Renesas Electronics is an automotive-grade evaluation board designed to validate the ISL78219 high-efficiency, current-mode non-synchronous boost regulator IC. It supports input voltage range 2.3V–5.5V, delivers regulated 12V output at up to 1.2A, and features jumper-selectable switching frequencies of 620kHz or 1.2MHz for transient response optimization in vehicle infotainment power rails.

For engineers reviewing the ISL78219EV1Z datasheet, ISL78219EV1Z pinout, ISL78219EV1Z application, or ISL78219EV1Z equivalent, this board enables rapid functional validation of the ISL78219's PWM control loop, frequency selection, enable logic, thermal performance, and ceramic-capacitor-based output filtering under real-world automotive input conditions.

Technical Context

The ISL78219EV1Z implements a complete reference design for the ISL78219 boost controller, including TDK CLF10060NID-100M-D 10µH shielded inductor, Fairchild FYD0504SATM Schottky diode, and Murata GRM31CR61C226KE15L 22µF X5R output capacitors. The board uses a fixed 12V feedback divider (R1 = 86.6kΩ, R2 = 10kΩ) with V_FB = 1.24V.

It provides dual-jumper configuration: J3 pins 1–3 select switching frequency (620kHz open / 1.2MHz short), and pins 2–4 control EN signal (short = enabled). The layout follows automotive PCB guidelines-ground plane separation, VIN decoupling at C2 (0.1µF), and isolation of FB/COMP networks from high-current LX paths.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	2.3V to 5.5V - matches automotive battery rail transients including cold-crank (2.3V) and load-dump recovery (≤5.5V).
Output Voltage	12.0V ±1% - set by precision 1.24V feedback reference and 86.6kΩ/10kΩ resistor divider.
Max Output Current	1.2A continuous - limited by ISL78219's 3.8A MOSFET current limit and thermal design with TDK 10µH inductor.
Switching Frequency	620kHz or 1.2MHz selectable via jumper - enables trade-off between efficiency (lower f_SW) and component size/transient response (higher f_SW).
Efficiency	Up to 94% at 5V_IN/12V_OUT/1.0A - achieved using low-ESR ceramic capacitors and optimized gate drive timing.
Operating Temperature	−40°C to +125°C - validated per AEC-Q100 requirements for under-hood automotive applications.

FAQ

What is the primary function of the ISL78219EV1Z?

The ISL78219EV1Z is an evaluation board-not a standalone IC-that demonstrates the operation of the ISL78219 boost regulator. It provides a fully assembled, tested, and characterized platform to verify input/output behavior, efficiency, thermal performance, and frequency-selectable operation under automotive voltage conditions. Engineers use the ISL78219EV1Z to validate system-level integration before committing to custom PCB design.

How do I configure the switching frequency on the ISL78219EV1Z?

On the ISL78219EV1Z, switching frequency is selected using jumper J3: shorting pins 1 and 3 configures the ISL78219 for 1.2MHz operation, while leaving them open sets it to 620kHz. This selection directly affects inductor size, output ripple, and transient response-critical for balancing EMI compliance and dynamic load handling in automotive applications using the ISL78219EV1Z.

Can the ISL78219EV1Z generate output voltages other than 12V?

Yes-the ISL78219EV1Z's output voltage can be adjusted by modifying the feedback resistor divider. With V_FB = 1.24V, changing R2 (currently 10kΩ) alters V_OUT; for example, 100kΩ yields ~5V and 619kΩ yields ~9V. Table 2 in the UG163 manual provides exact R2 values. The ISL78219EV1Z supports reconfiguration but requires capacitor voltage rating verification for outputs >12V.

What are the key components included on the ISL78219EV1Z board?

The ISL78219EV1Z integrates the ISL78219 TDFN-10 IC, TDK CLF10060NID-100M-D 10µH shielded inductor, Fairchild FYD0504SATM 40V/5A Schottky diode, three Murata 22µF/16V X5R output capacitors (C1/C3/C6), and precision automotive-grade resistors (Panasonic ERJ-2RKF series). All components meet AEC-Q200 stress testing requirements for automotive deployment.

Is the ISL78219EV1Z RoHS compliant and lead-free?

Yes-the ISL78219EV1Z is Pb-Free and RoHS compliant, as confirmed in Section 1.1 of the UG163 User's Manual. Its PCB, passives, and IC packaging adhere to EU Directive 2011/65/EU. The board uses AVX, TDK, Murata, and Panasonic components qualified for automotive use, and all solder mask, silkscreen, and substrate materials comply with RoHS substance restrictions.
