Product details
Overview
ISL6526EVAL2 from Renesas Electronics is a ready-to-use evaluation board for the ISL6526CR 300kHz synchronous buck PWM controller in 16-lead MLFP package, configured for 2.5V/5A output with fixed regulation, input voltage range 3.3V–5V, and Kelvin probe points for CPVOUT, CT1, and ENABLE signals.
For engineers reviewing the ISL6526EVAL2 datasheet, ISL6526EVAL2 pinout, ISL6526EVAL2 application, or ISL6526EVAL2 equivalent, this board enables rapid validation of embedded DC-DC converter designs requiring tight output regulation, sink/source current capability, and MOSFET gate drive performance without hardware modification.
Technical Context
The ISL6526EVAL2 implements a complete synchronous-rectified buck converter using the ISL6526CR controller, which integrates a high-accuracy 0.8V reference, error amplifier, 300kHz fixed-frequency oscillator, over-current protection, and dual MOSFET drivers. It supports both sourcing and sinking current operation under load.
Board-level design includes a 1μH inductor (Panasonic ETQP6F1R0SFA), dual-MOSFET stage (Fairchild ITF86110DK8), and output filter with three 150μF aluminum polymer capacitors (Panasonic EEF-UE0J151R). Input bias is derived from the 3.3V rail via internal charge pump.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Controller IC | ISL6526CR - 300kHz fixed-frequency synchronous buck PWM controller in 16-lead 5×5mm MLFP package. |
| Output Voltage | Fixed 2.5V - pre-configured via resistor divider (R1=9.76kΩ, R2=6.49kΩ); no potentiometer adjustment. |
| Max Output Current | 5A continuous - validated for both sourcing and sinking operation with thermal management via PCB copper area. |
| Input Voltage Range | 3.3V to 5V - accepts standard logic-supply rails; bias generated internally via charge pump from VCC. |
| Probe Points | TP1 (CT1), TP2 (ENABLE), TP3 (CPVOUT) - Kelvin-connected test points for accurate signal measurement without lead resistance error. |
| Switching Frequency | 300kHz - fixed oscillator frequency enabling optimized trade-off between efficiency and component size. |

FAQ
What is the primary function of the ISL6526EVAL2 evaluation board?
The ISL6526EVAL2 evaluation board is a fully assembled, ready-to-use reference design that demonstrates the operation of the ISL6526CR 300kHz synchronous buck PWM controller. It delivers a fixed 2.5V output at up to 5A, supports both sourcing and sinking current, and includes Kelvin probe points for precise signal monitoring. The ISL6526EVAL2 requires no modifications for immediate functional evaluation.
Does the ISL6526EVAL2 support adjustable output voltage?
No, the ISL6526EVAL2 provides a fixed 2.5V output determined by its onboard resistor divider (R1=9.76kΩ, R2=6.49kΩ). Unlike the ISL6527EVAL2, it does not include a potentiometer or external reference input. Output voltage adjustment would require modifying the feedback network - a change not supported by the default ISL6526EVAL2 configuration.
Which controller IC is populated on the ISL6526EVAL2 board?
The ISL6526EVAL2 board is populated with the ISL6526CR - a 300kHz version of the ISL6526 synchronous buck PWM controller in a 16-lead 5×5mm MLFP package. This matches the "300kHz / ISL6526CR / 16 ld MLFP" entry in Table 1 of AN1021, confirming exact part identity and package mapping.
Can the ISL6526EVAL2 be used to evaluate sink-current capability?
Yes, the ISL6526EVAL2 explicitly supports sinking current operation as confirmed in AN1021: "Both the ISL6526 and the ISL6527 are capable of regulating the output voltage while the DC-DC converter is sinking current." Test instructions in the application note detail how to connect an external load between J1 (3.3V) and J3 (VOUT) to exercise sink-mode behavior - a key feature validated on the ISL6526EVAL2.
What input voltage range is supported by the ISL6526EVAL2?
The ISL6526EVAL2 accepts an input voltage range of 3.3V to 5V, applied via terminals J1 (3.3V) and J2 (GND). This range aligns with the ISL6526CR's specified bias voltage capability and enables direct use with common logic-supply rails. Operation outside this range is not supported and may damage the ISL6526EVAL2 or violate controller specifications.
