Product details
Overview
ISL69223IRAZ from Renesas is a digital dual-output, 4-phase PWM controller supporting flexible phase assignment (e.g., 3+1 or 2+2) with PMBus v1.3 interface, ±0.5% closed-loop system accuracy via differential remote sensing, up to 2MHz switching frequency, and synthetic current modulation for fast transient response - deployed in high-performance DDR memory and AI accelerator power rails.
For engineers reviewing the ISL69223IRAZ datasheet, ISL69223IRAZ pinout, ISL69223IRAZ application, or ISL69223IRAZ equivalent, key selection criteria include phase configurability (X+Y ≤ 4), PMBus programmability, diode emulation for light-load efficiency, per-phase fault management, and compatibility with Renesas smart power stages including ISL99380 and ISL99360.
Technical Context
The ISL69223IRAZ implements Renesas' proprietary digital synthetic current modulation architecture, enabling zero-latency current synthesis and dual-edge PWM control with optional diode braking - delivering industry-leading transient response without external compensation components. It supports auto phase add/drop and PFM mode across full load range.
Its integrated telemetry manager monitors VOUT, IOUT, VIN, temperature (via TEMP0/TEMP1), and power metrics via PMBus, while the Black Box recorder captures first-fault status. Fault protection includes pulse-by-pulse OCP, overvoltage/undervoltage, thermal warning (nVRHOT), and catastrophic failure detection (CFP).

FAQ
What is the maximum supported switching frequency for the ISL69223IRAZ?
The ISL69223IRAZ supports up to 2MHz switching frequency, enabling high-density power designs with smaller magnetics and reduced output capacitance. This capability is confirmed in the datasheet's Electrical Specifications section and validated across –40°C to +125°C operating range. The ISL69223IRAZ maintains stable regulation and thermal performance at 2MHz when paired with appropriate gate drivers and smart power stages such as ISL99380.
Does the ISL69223IRAZ support both PMBus and AVSBus interfaces?
No, the ISL69223IRAZ supports PMBus v1.3 only - not AVSBus. This is explicitly stated in the datasheet's Table 1 (Key Differences Between Family of Parts) and confirmed by its supported command set (e.g., OPERATION, VOUT_COMMAND, READ_IOUT). AVSBus support is reserved for higher-phase variants like ISL68233 and ISL68239. The ISL69223IRAZ relies exclusively on PMBus for configuration, telemetry, and fault reporting.
How many user configurations can be stored in the ISL69223IRAZ's non-volatile memory?
The ISL69223IRAZ stores up to 16 user-defined configurations in on-chip non-volatile memory (NVM), as documented in the Features section and verified in Section 3.3 ("Selecting the User Configurations"). Each configuration retains full settings including phase assignment, voltage targets, OCP limits, and telemetry parameters - allowing field updates without host processor involvement. This capability is integral to the ISL69223IRAZ's deployment in systems requiring multiple power states or firmware-upgradable power profiles.
What current sensing methods does the ISL69223IRAZ support?
The ISL69223IRAZ supports three current sensing methods: smart power stage (SPS) current monitor outputs, DCR sensing using external RC networks, and discrete resistor sensing. This flexibility is enabled by the CS[3:0]/CSRTN[3:0] differential input pairs and confirmed in the Functional Pin Descriptions (Page 10) and Layout Considerations (Page 28). The ISL69223IRAZ automatically adapts gain and filtering based on selected method - ensuring accurate OCP and load-line regulation regardless of implementation choice.
Is the ISL69223IRAZ pin-compatible with other members of the ISL6822x family?
Yes, the ISL69223IRAZ is pin-compatible with the ISL68223IRAZ and ISL68222IRAZ - all use the same 40-lead 5x5mm QFN package (L40.5x5D) and share identical pin functions, layout requirements, and thermal pad design. This compatibility is confirmed in the Ordering Information table (Page 8) and Package Outline Drawing (Page 97). However, phase count and bus protocol differ: ISL68222IRAZ supports 5 phases and ISL68233IRAZ adds AVSBus - so firmware and configuration must be validated per part number.
