Product details
Overview
ISL98602IRAAZ-TK from Renesas (formerly Intersil) is a 5-channel integrated LCD power supply IC for large-panel displays, featuring a 5.5A boost converter for AVDD up to 19V, dual charge pumps (VON up to +36V/120mA, VOFF down to −10V/120mA), two synchronous buck stages (Buck1: 3.3V/2.5V with 2.0A peak FETs; Buck2 controller for 0.9–2.0V), integrated VON slice circuitry, and power-good signaling. It operates at 1.3MHz with full protection suite and targets LCD TV timing controller (TCON) power delivery.
For engineers reviewing the ISL98602IRAAZ-TK datasheet, ISL98602IRAAZ-TK pinout, ISL98602IRAAZ-TK application, or ISL98602IRAAZ-TK equivalent, key selection criteria include AVDD boost current capability, VON/Voff charge pump voltage ranges, synchronous buck regulation accuracy, integrated VON slicing for flicker reduction, and thermal performance in 40-lead 6×6 QFN packaging.
Technical Context
The ISL98602IRAAZ-TK integrates five independent regulated outputs: a high-current boost stage with far-side feedback and OVP for AVDD generation; two logic-supply buck converters-one fully integrated (Buck1), one controller-only (Buck2) with external MOSFET drive; and dual charge pumps with full-frequency switching and integrated drivers for VON and VOFF. The VON slice function processes the VON output to reduce display flicker.
It implements automatic start-up sequencing across all rails, uses internal 1.3MHz clocking for all switching stages, and embeds comprehensive protection including UVLO, UVP, OVP, OCP, and OTP. All channels share a common −40°C to +85°C ambient operating range and RoHS-compliant 40-lead QFN package with exposed thermal pad.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LCD panel power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RTQ2132B-QA | Single-chip solution with integrated 4-channel DC/DC but no VON slice; max VON = +32V, no VOFF generation. | Limited to smaller panels (<32") lacking flicker-critical VON shaping; requires external VOFF circuitry. | Select when panel size and flicker sensitivity permit simplified architecture and lower cost. |
| TPS65150RGER | 3-channel LCD PMIC (AVDD/VON/VOFF); no buck regulators; fixed VON/Voff voltages; no VON slice or PG function. | Suitable only for basic LCD modules without TCON logic power or sequencing needs; lacks integrated logic rail generation. | Choose for legacy designs using discrete logic supply and minimal feature set. |
Compared with RTQ2132B-QA and TPS65150RGER, the ISL98602IRAAZ-TK uniquely combines five regulated outputs-including flicker-reducing VON slice, dual logic bucks, and power-good-with full protection and sequencing in one package, making it optimal for large-panel, high-reliability LCD TV systems.

FAQ
What is the maximum output current capability of the AVDD boost converter in the ISL98602IRAAZ-TK?
The ISL98602IRAAZ-TK AVDD boost converter delivers up to 5.5A continuous output current, supporting high-power source driver ICs in large-panel LCD applications. This rating is validated under typical thermal conditions with proper PCB copper area and airflow. The ISL98602IRAAZ-TK integrates an internal 5.5A boost FET and uses far-side feedback to maintain regulation under dynamic load steps.
Does the ISL98602IRAAZ-TK support programmable VON and VOFF voltages?
The ISL98602IRAAZ-TK provides fixed VON and VOFF output voltages-up to +36V and down to −10V respectively-with 120mA current capability per rail. These values are internally trimmed and not user-adjustable via external resistors or digital interface. The ISL98602IRAAZ-TK does include integrated VON slice circuitry to shape the VON waveform, but voltage levels themselves are factory-set.
How does the VON slice function in the ISL98602IRAAZ-TK improve display performance?
The VON slice function in the ISL98602IRAAZ-TK modifies the VON charge pump output waveform to reduce vertical line flicker in large LCD panels. It achieves this by dynamically adjusting rise/fall timing and amplitude profile based on internal control logic. This analog post-processing is unique to the ISL98602IRAAZ-TK and eliminates need for external flicker compensation circuits.
What protection features are integrated into the ISL98602IRAAZ-TK?
The ISL98602IRAAZ-TK integrates UVLO, UVP, OVP, OCP, and OTP protection across all functional blocks. Each protection circuit operates independently per channel-for example, OCP triggers cycle-by-cycle on Buck2 phase nodes, while OVP monitors AVDD at the far-side feedback point. These safeguards ensure robust operation in consumer and industrial LCD TV environments without external supervision.
Is the ISL98602IRAAZ-TK pin-compatible with other members of the ISL9860x family?
The ISL98602IRAAZ-TK shares the same 40-lead 6×6 QFN package and core pinout with ISL98601 and ISL98603 variants, but voltage configurations and feature sets differ. For example, ISL98601 omits the VON slice and Buck2 controller. Pin compatibility does not guarantee functional drop-in replacement; system-level validation of sequencing, feedback, and protection behavior is required before substitution.
