Product details
Overview
ISL98607IRTZ-T from Renesas is a highly integrated dual-rail power supply IC for small-display biasing, combining a synchronous boost regulator (VBST), a positive LDO (VP), and an inverting charge pump (VN) in a single 20-lead TQFN package. It delivers ±5.0V default outputs (adjustable to ±5.7V in 50mV steps via I²C), supports 2.8V–4.4V Li-ion input, achieves >85.5% efficiency at 12mA load, and operates across –40°C to +85°C ambient.
For engineers reviewing the ISL98607IRTZ-T datasheet, ISL98607IRTZ-T pinout, ISL98607IRTZ-T application, or ISL98607IRTZ-T equivalent, this device is selected for compact TFT-LCD display power in smartphones and handhelds where PCB area (<21mm² solution), low shutdown current (1µA), and programmable rail tuning are critical design requirements.
Technical Context
The ISL98607IRTZ-T implements a three-stage architecture: a 1.45MHz synchronous boost converter generates VBST (5.15–6.0V), which feeds both a linear VP regulator (5.0–5.7V, 100mV dropout at 100mA) and a 1.45MHz inverting charge pump producing VN (–5.0 to –5.7V). All compensation, feedback, and discharge resistors are fully integrated.
I²C control (400kHz Fast-Mode, address 0x29) enables real-time adjustment of all output voltages, enable sequencing (ENP/ENN), and fault monitoring. The device includes undervoltage lockout (2.52V threshold), thermal shutdown (130°C), and dedicated protection for VP/VN rails (0.6× nominal UVP).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8V–4.4V - matches single-cell Li-ion battery operating window without external pre-regulation. |
| VP Output Voltage | +5.0V to +5.7V (50mV steps) - adjustable LDO rail for TFT gate driver positive bias with <±2% accuracy. |
| VN Output Voltage | –5.0V to –5.7V (50mV steps) - programmable negative rail for TFT common electrode or source driver bias. |
| Efficiency | >85.5% at 12mA load between VP and VN - enables extended battery life in always-on display segments. |
| Shutdown Current | 1µA - minimizes quiescent drain during display sleep/standby modes. |
| Solution PCB Area | 21mm² - achieved using integrated FETs, compensation, and compact 3×4mm TQFN package. |
| Ambient Temp Range | –40°C to +85°C - qualified for consumer handheld and automotive infotainment display environments. |
Pinout & Package
ISL98607IRTZ-T is housed in a Pb-free, RoHS-compliant 20-lead 3×4mm TQFN package (package drawing L20.3x4A) with exposed thermal pad. Pin assignment is optimized for low-noise layout: separate AGND and PGND pins, dedicated VIN, VBST, CP, CN, VP, VN, and I²C (SCL/SDA) interfaces.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 13) | Main input supply | Accepts 2.8–4.4V Li-ion; requires 10µF decoupling to PGND for stable boost operation. |
| VBST (Pin 1) | Boost output rail | Supplies power to both VP LDO and VN charge pump; must be connected to VBSTCP (Pin 2). |
| VP (Pins 15,16) | Positive regulated output | Dual-pin output requiring PCB shorting; delivers up to 100mA with 100mV dropout at full load. |
| VN (Pin 6) | Negative regulated output | Charge-pump-derived rail; connects to VSUB (Pin 7) to ensure substrate biasing at most negative potential. |
| CP (Pin 3) / CN (Pin 5) | Charge pump flying capacitor nodes | Form voltage-inverting network with external capacitor; CP tied to VBST, CN referenced to VN. |
| ENP (Pin 9) / ENN (Pin 12) | Enable inputs | Separate controls for VP (ENP) and VBST/VN (ENN); internal 200kΩ pull-down ensures safe default-off state. |
| SCL/SDA (Pins 8,10) | I²C interface | Supports 400kHz Fast-Mode; address 0x29; requires external pull-ups for bus compliance. |
| PGND (Pins 15,16,4) | Power ground return | Dedicated low-impedance path for boost and charge pump switching currents; separate from AGND. |
| AGND (Pin 14) | Analog reference ground | Reference for feedback, I²C, and enable logic; must be isolated from noisy PGND traces. |
| VSUB (Pin 7) | Substrate connection | Mandatory tie to VN to prevent latch-up; establishes lowest potential node on die. |
Key Features
| Feature | Design Value |
|---|---|
| Fully integrated synchronous FETs | Eliminates external MOSFETs and reduces conduction losses in both boost and charge pump stages. |
| On-chip compensation and feedback | Removes need for external loop compensation components, cutting BOM count and enabling 21mm² total solution size. |
| I²C-adjustable output voltages | Enables dynamic rail tuning for display brightness/contrast optimization without hardware changes. |
| Integrated VP/VN discharge resistors | Ensures rapid rail collapse during shutdown (RDCH_VP = 80Ω, RDCH_VN = 35Ω), preventing ghosting in LCD panels. |
| Dual enable control (ENP/ENN) | Allows independent sequencing of VP and VBST/VN rails to meet TFT panel power-up timing requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail display power applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the default output voltage configuration of the ISL98607IRTZ-T?
The ISL98607IRTZ-T powers up with VP = +5.0V, VN = –5.0V, and VBST = +5.15V as factory-default settings. These values are stored in nonvolatile register defaults and can be modified via I²C commands to any value within the ±5.0V to ±5.7V range (50mV steps) without requiring external components or hardware changes.
How does the ISL98607IRTZ-T manage power sequencing for display panels?
The ISL98607IRTZ-T provides independent enable control via ENP (for VP) and ENN (for VBST/VN), allowing precise sequencing of positive and negative rails. This prevents latch-up or image artifacts during panel power-up/down. Soft-start times (0.7–2ms per rail) are internally controlled and synchronized to minimize transient overshoot on both VP and VN outputs.
Can the ISL98607IRTZ-T operate from a 3.3V supply?
Yes - the ISL98607IRTZ-T supports an input voltage range of 2.8V to 4.4V, fully covering standard 3.3V system rails and single-cell Li-ion batteries (2.8V–4.4V). At 3.3V input, it maintains >85.5% efficiency at 12mA load and delivers stable ±5V outputs through its integrated boost and charge pump stages.
What package type is used for the ISL98607IRTZ-T?
The ISL98607IRTZ-T uses a 20-lead, 3mm × 4mm TQFN package (RoHS-compliant, package drawing L20.3x4A) with exposed thermal pad. This differs from the WLCSP variant (ISL98607EIAZ-T); the TQFN offers easier assembly, better thermal performance via PCB copper pour, and compatibility with standard reflow profiles.
Does the ISL98607IRTZ-T include built-in protection features?
Yes - the ISL98607IRTZ-T integrates undervoltage lockout (2.52V threshold), thermal shutdown (130°C trip, 120°C hysteresis), VP/VN undervoltage protection (0.6× nominal), and current limiting on VBST (1.4A typical). These protections operate autonomously without firmware intervention, ensuring robust operation in unattended handheld and portable systems.
