Product details
Overview
ISL98602IRABZ-TK from Renesas (formerly Intersil) is a 5-channel LCD display power management IC integrating a 5.5A boost converter for AVDD (up to 19V), dual charge pumps for VON (up to +36V/120mA) and VOFF (down to −10V/120mA), two synchronous buck regulators (Buck1: 3.3V/2.5V, 2.0A peak; Buck2 controller: 0.9–2.0V), VON slicing circuitry, and Power Good signaling - deployed in large-panel LCD TVs.
For engineers reviewing the ISL98602IRABZ-TK datasheet, ISL98602IRABZ-TK pinout, ISL98602IRABZ-TK application, or ISL98602IRABZ-TK equivalent, key selection considerations include AVDD regulation accuracy with far-side feedback, integrated VON slice for flicker reduction, 1.3MHz switching frequency enabling compact magnetics, and full protection suite (OVP/UVP/OTP/OCP/UVLO).
Technical Context
The ISL98602IRABZ-TK implements a high-power boost architecture with internal 5.5A FET and delay-switch feedback loop for improved AVDD load regulation; its VON charge pump operates at full 1.3MHz switching frequency and feeds an on-die slicing circuit that dynamically adjusts output timing to suppress panel flicker.
Buck1 integrates 2.3A synchronous FETs and fixed/adjustable 3.3V or 2.5V output with soft-start; Buck2 is a controller-only stage supporting external MOSFETs for 0.9–2.0V logic rails, featuring cycle-by-cycle overcurrent protection and adjustable current limit via external sense resistor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 9.5V to 15.0V - supports standard 12V LCD panel supply rails with ±10% tolerance margin. |
| AVDD Boost Output | Up to 19V @ 5.5A - powers TFT source drivers requiring high-voltage analog rail with far-side feedback compensation. |
| VON Charge Pump | +36V @ 120mA - drives gate-on voltage for large-area LCD panels; includes integrated slicing for flicker suppression. |
| VOFF Charge Pump | −10V @ 120mA - supplies gate-off bias; complementary to VON for full gate driver swing control. |
| Buck1 Output | 3.3V or 2.5V @ 2.0A peak - powers TCON logic and interface circuits; integrates synchronous FETs and soft-start. |
| Buck2 Controller Range | 0.9V to 2.0V - enables flexible core voltage scaling for embedded microcontrollers or timing controllers. |
| Switching Frequency | 1.3MHz - allows use of small 1µH inductors and 10µF ceramic output capacitors per channel. |
| Operating Temperature | −40°C to +85°C ambient - qualified for consumer TV chassis thermal environments without derating. |
Pinout & Package
Package: 40-lead, 6mm × 6mm, 0.5mm pitch QFN with exposed thermal pad (RoHS-compliant, Pb-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Key Features
| Feature | Design Value |
|---|---|
| VON Slice Function | On-die timing adjustment circuit reduces vertical line flicker by synchronizing VON pulse width with panel refresh rate and data loading latency. |
| Far-Side AVDD Feedback | Feedback sensed at remote AVDD capacitor improves load regulation to ±1.5% across 0–5.5A load step, critical for uniform brightness. |
| Automatic Sequencing | Internal state machine sequences AVDD → VON/VOFF → Buck1 → Buck2 with programmable delays, eliminating need for external sequencer IC. |
| Comprehensive Protection | Integrated UVLO, UVP, OVP, OCP (cycle-by-cycle for Buck2), and OTP prevent damage during fault conditions without external components. |
| Thermal Pad Design | Exposed thermal pad under QFN package enables direct PCB copper pour connection for ≤35°C/W junction-to-board thermal resistance. |

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-QT | Single 4-channel PMIC (no VON slice); 3.0A boost; supports only 3.3V/1.8V bucks; no far-side AVDD feedback. | Lacks flicker suppression capability; requires external VON timing control; suited for smaller panels (<32") with simpler TCON. | Select when VON slicing is unnecessary and cost sensitivity outweighs flicker performance requirements. |
| TPS65150RGER | 3-channel solution (boost + dual charge pumps); no buck regulators; no Power Good or sequencing logic; 2.5A boost. | Requires external logic rails and sequencer; limited to AVDD/VON/VOFF only; no integrated TCON enable signaling. | Choose for legacy designs where logic rails are already supplied separately and flicker control is handled externally. |
Compared with RTQ2132B-QT and TPS65150RGER, the ISL98602IRABZ-TK uniquely integrates VON slicing, far-side AVDD regulation, automatic sequencing, and dual-buck capability - making it the only single-chip solution for flicker-critical large-panel LCD TVs requiring full rail integration and TCON coordination.

FAQ
What is the primary function of the ISL98602IRABZ-TK in an LCD TV system?
The ISL98602IRABZ-TK serves as the central power management IC for large-panel LCD TVs, generating and regulating five critical voltages: AVDD (up to 19V), VON (+36V), VOFF (−10V), Buck1 (3.3V/2.5V), and Buck2 (0.9–2.0V). It also provides VON slicing for flicker reduction and Power Good signaling to enable the timing controller after full rail stabilization. The ISL98602IRABZ-TK replaces up to 15 discrete components in traditional LCD power architectures.
Does the ISL98602IRABZ-TK support adjustable output voltages for its buck regulators?
Yes, Buck1 output is factory-configured for either 3.3V or 2.5V and can be adjusted using an external feedback resistor network; Buck2 is a controller-only stage with fully adjustable output from 0.9V to 2.0V via external resistive divider and external MOSFETs. The ISL98602IRABZ-TK does not support programmable AVDD, VON, or VOFF voltages - those are fixed per variant.
How does the VON slice function in the ISL98602IRABZ-TK reduce display flicker?
The ISL98602IRABZ-TK's integrated VON slice circuit dynamically trims the VON pulse width and timing based on real-time panel load and TCON synchronization signals (GHC/GHON pins), minimizing ΔVON variation across scan lines. This reduces vertical banding and improves grayscale uniformity. The ISL98602IRABZ-TK achieves <±0.8V VON stability over temperature, directly lowering perceptible flicker in large-area displays.
What thermal management features does the ISL98602IRABZ-TK include?
The ISL98602IRABZ-TK uses a 40-lead 6×6 mm QFN package with an exposed thermal pad designed for direct PCB copper pour attachment. Its internal thermal shutdown (OTP) activates at 150°C junction temperature, and the layout-optimized pinout separates PGND returns to minimize thermal coupling between power stages. The ISL98602IRABZ-TK sustains full 5-channel operation at 75°C ambient with proper board-level thermal design.
Is the ISL98602IRABZ-TK pin-compatible with other members of the ISL9860x family?
No, the ISL98602IRABZ-TK is not pin-compatible with ISL98601 or ISL98603 variants due to differences in channel count, pin assignment (e.g., missing GHC/GHON on ISL98601), and internal configuration. Each ISL9860x variant has unique pinout and footprint - the ISL98602IRABZ-TK requires its specific 40-lead QFN layout with dedicated PGND routing and thermal pad connection.
