Product details
Overview
ISL98602IRABZ-T 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: 0.9V–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 ISL98602IRABZ-T datasheet, ISL98602IRABZ-T pinout, ISL98602IRABZ-T application in LCD TV power sequencing, or ISL98602IRABZ-T equivalent for multi-rail display bias supplies, this page provides verified functional identity, validated pin roles, confirmed thermal and protection specifications, and real-world substitution guidance aligned with manufacturer-released variants.
Technical Context
The ISL98602IRABZ-T integrates five independent power rails within a single 40-lead QFN: AVDD is generated by a high-current 5.5A boost stage with far-side feedback and OVP; VON and VOFF are derived from dedicated charge pumps operating at full 1.3MHz switching frequency, with VON further conditioned by on-die slicing to suppress panel flicker.
Buck1 delivers fixed 3.3V or 2.5V logic voltage using internal 2.3A synchronous FETs and soft-start; Buck2 is a controller-only stage supporting adjustable 0.9V–2.0V output via external MOSFETs, with integrated OCP. All rails feature coordinated startup sequencing and share UVLO, UVP, OVP, OCP, and OTP protection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-rail LCD bias supply applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL98601IRABZ-T | Single-buck configuration (no Buck2 controller); lacks VON slice; identical AVDD/VON/VOFF specs | Suitable only for panels requiring one logic rail; not compatible with dual-voltage TCONs | Select when design uses only 3.3V logic and eliminates need for adjustable Buck2 output |
| RTQ2132BGQW | 3-channel solution (boost + dual buck); no charge pumps; no VON slice; max AVDD = 16V | Targets smaller panels without gate driver bias requirements; requires external VON/VOFF generation | Choose for cost-sensitive 32″–43″ TVs where external charge pump ICs are acceptable |
Compared with ISL98602IRABZ-T, ISL98601IRABZ-T reduces integration by removing Buck2 control and VON slicing-ideal for simpler panels-while RTQ2132BGQW trades charge pump functionality for lower BOM cost and smaller footprint, necessitating external bias generation for large-panel gate drivers.

FAQ
What is the primary function of the ISL98602IRABZ-T in an LCD TV system?
The ISL98602IRABZ-T serves as the central power management IC for large-panel LCD TVs, generating five critical bias rails: AVDD (up to 19V), VON (+36V), VOFF (−10V), Buck1 (3.3V/2.5V), and Buck2 (0.9V–2.0V). Its integrated VON slice and Power Good signal directly support timing controller (TCON) sequencing and flicker reduction-core functions confirmed in the FN7699 datasheet for ISL98602IRABZ-T.
Does the ISL98602IRABZ-T support adjustable output voltages for all channels?
No. The ISL98602IRABZ-T offers fixed AVDD, VON, and VOFF outputs determined by internal resistor networks, while Buck1 supports factory-selectable 3.3V or 2.5V via pin strapping. Only Buck2 is fully adjustable (0.9V–2.0V) using external feedback resistors-this configurability is explicitly documented in the "Electrical Specifications" table of the ISL98602IRABZ-T datasheet.
How does the VON slice function improve display performance in the ISL98602IRABZ-T?
The ISL98602IRABZ-T integrates dedicated VON slice circuitry that conditions the +36V charge pump output to reduce low-frequency ripple, directly mitigating vertical banding and flicker on large TFT panels. This analog slicing replaces external RC filters, improving response time and eliminating component aging effects-details confirmed in the "Features" and "Functional Description" sections of the ISL98602IRABZ-T datasheet.
What thermal management features does the ISL98602IRABZ-T include?
The ISL98602IRABZ-T uses a 40-lead 6×6 mm QFN package with an exposed thermal pad, enabling direct PCB copper pour attachment for efficient heat dissipation. It incorporates thermal shutdown (OTP) with hysteresis and operates across −40°C to +85°C ambient, sustaining full 120mA VON/VOFF output at maximum temperature-specifications validated in the "Absolute Maximum Ratings" and "Thermal Characteristics" tables of the ISL98602IRABZ-T datasheet.
Can the ISL98602IRABZ-T replace discrete boost and charge pump solutions?
Yes-the ISL98602IRABZ-T integrates a 5.5A boost converter, dual high-current charge pumps, two synchronous buck stages, VON slicing, and Power Good into one QFN package. It replaces ≥7 discrete ICs and passives in typical large-panel LCD power trees, reducing layout area by ~40% and improving cross-regulation-performance claims substantiated by the "Typical Application Circuit" and BOM comparison in the ISL98602IRABZ-T datasheet.
