Product details
Overview
ISL9113EI9Z-T from Intersil is a 5.1V fixed-output, synchronous boost converter optimized for portable HDMI and USB-OTG power rails. It operates from 0.8V–4.7V input (e.g., single-cell Li-ion), delivers up to 500mA at 5.1V from 3.0V input, features 1.8MHz switching, 20µA quiescent current in skip mode, and integrates N- and P-channel MOSFETs with 0.20Ω/0.35Ω RDS(ON).
For engineers reviewing the ISL9113EI9Z-T datasheet, ISL9113EI9Z-T pinout, ISL9113EI9Z-T application, or ISL9113EI9Z-T equivalent, key selection criteria include its 6-bump WLCSP package (0.8mm × 1.36mm), output disconnect during shutdown, undervoltage lockout (0.70V), thermal shutdown (150°C), and compatibility with low-profile 2.2µH inductors and ceramic capacitors.
Technical Context
The ISL9113EI9Z-T implements peak current-mode PWM control with internal compensation and an integrated 1.8MHz oscillator. Its synchronous rectification replaces Schottky diodes using matched N- and P-channel MOSFETs, enabling >90% efficiency and full output disconnect during shutdown via reverse-polarity body-diode control.
It supports two operating modes: continuous 1.8MHz PWM under medium-to-heavy loads and skip mode under light loads-triggered after eight consecutive zero-current crossings-to reduce quiescent current to 20µA while maintaining regulation and fast load-transient response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 5.1V ±1.2% (4.96–5.2V) at 1mA–50mA load; enables direct USB-OTG VBUS compliance without external feedback resistors. |
| Input voltage range | 0.8V–4.7V; supports single-cell Li-ion (2.7–4.2V), NiMH/NiCd (0.9–1.4V/cell), and three-alkaline (1.2–1.5V/cell) battery configurations. |
| Switching frequency | 1.7–2.2MHz (WLCSP); allows use of 2.2µH inductors and compact 4.7µF ceramic capacitors, minimizing solution footprint to <15mm². |
| Peak switch current limit | 1.3A typical; sets maximum inductor current and defines safe operating area for 2.2µH inductors with ≥1.5A saturation rating. |
| Quiescent current | 20µA typical in skip mode; extends battery runtime in standby states of portable HDMI transmitters and OTG peripherals. |
| Shutdown current | ≤2µA; ensures near-zero battery drain when disabled via EN pin, critical for always-on system power management. |
| Thermal protection | 150°C trip with 25°C hysteresis; prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
ISL9113EI9Z-T is housed in a 6-bump WLCSP (0.8mm × 1.36mm, 0.4mm pitch) with exposed silicon die top-side and solder bumps on bottom. The package has no exposed thermal pad; thermal dissipation relies on bump-to-PCB conduction and board copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A2 | PGND | Power ground return for high-switching-current paths; must be connected directly to solid GND plane with minimum trace inductance. |
| B1 | VBAT | Main input supply pin; requires local 4.7µF ceramic capacitor between VBAT and PGND to suppress high-frequency ripple. |
| B2 | SW | Internal switching node connecting to inductor; carries high dv/dt and di/dt; routing must avoid sensitive analog traces (e.g., FB). |
| A1 | VOUT | Regulated 5.1V output; supplies downstream USB-OTG or HDMI sink; requires local 4.7µF ceramic capacitor to ground for stability. |
| C2 | FAULT | Open-drain fault indicator (active-low); asserts during overtemperature, short circuit, or low-battery conditions; requires pull-up resistor. |
| C1 | EN | Active-high enable input (1.2V logic threshold); disables all switching and disconnects VOUT from VBAT when low, reducing IQ to ≤2µA. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated N- and P-channel MOSFETs (0.20Ω/0.35Ω RDS(ON)) eliminate Schottky losses, enabling >90% efficiency and full output disconnect during shutdown. |
| Output disconnect | Active during shutdown to prevent battery drain through load; no external MOSFET or controller required for true input–output isolation. |
| Skip mode operation | Reduces quiescent current to 20µA at light loads while maintaining regulation; improves light-load efficiency by >25% vs. forced-PWM operation. |
| Internal voltage divider | Eliminates external feedback resistors for 5.1V fixed output (ISL9113EI9Z-T), reducing BOM count and layout sensitivity versus adjustable versions. |
| Undervoltage lockout | 0.70V threshold prevents startup from depleted batteries, avoiding brownout instability and ensuring reliable cold-start from 0.8V input. |
Applications
| Portable HDMI Transmitters | USB On-The-Go (OTG) Hosts |
|---|---|

Use Scenario: Powering BLE SoCs or environmental sensors (e.g., humidity/temperature) from primary alkaline cells in smart home nodes. IC Role / Device Role / Timing Role: Input-voltage-agnostic boost stage adapting 0.8–1.5V per cell to consistent 5.1V system rail. Use Value: 1.8MHz switching enables tiny 2.2µH inductor and 4.7µF caps, reducing total solution size to <12mm²-critical for PCB-constrained sensor modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61230ARNSR | Fixed 5.0V output; 1.5MHz switching; 0.25Ω/0.45Ω MOSFET RDS(ON); 12-bump WLCSP (1.6mm × 1.6mm). | Lower efficiency at 1.2V input due to higher RDS(ON); larger footprint limits ultra-compact designs. | Select if 5.0V (not 5.1V) output suffices and board space permits larger WLCSP. |
| MAX17222ELT+T | Adjustable output (0.6–5.25V); 1.2MHz switching; 0.18Ω/0.32Ω RDS(ON); 6-bump WLCSP (0.8mm × 1.2mm). | Requires external feedback resistors; lacks FAULT pin and OVP; no output disconnect during shutdown. | Select when programmable output voltage is needed and fault reporting/output isolation are not required. |
Compared with TPS61230ARNSR and MAX17222ELT+T, the ISL9113EI9Z-T provides tighter 5.1V output accuracy, integrated fault signaling, true output disconnect, and superior light-load efficiency-making it optimal for USB-OTG and portable HDMI where regulation precision and battery preservation are critical.

FAQ
What is the output voltage tolerance of the ISL9113EI9Z-T?
The ISL9113EI9Z-T delivers a fixed 5.1V output with ±1.2% tolerance (4.96V to 5.2V) across temperature and load (1mA–50mA). This specification is verified per datasheet page 6, Electrical Specifications table, under "ILOAD = 1mA or 50mA, 5.1V WLCSP Fixed version" test condition.
Does the ISL9113EI9Z-T support output disconnect during shutdown?
Yes, the ISL9113EI9Z-T fully disconnects VOUT from VBAT during shutdown via internal reverse-polarity control of the P-channel MOSFET body diode. This feature eliminates battery drain through the load and is confirmed in the "Synchronous Rectifier" section (page 7) and "Typical Application Circuit" (page 8) of the FN8313 datasheet.
What is the minimum input voltage required for the ISL9113EI9Z-T to start up?
The ISL9113EI9Z-T starts up reliably at a minimum input voltage of 2.8V (typical) when EN is asserted at 1.2V, as specified in the "Start-up Voltage" parameter (VMIN) on page 6 of the datasheet. However, it can operate continuously down to 0.8V once running, enabling deep battery discharge utilization.
Which package does the ISL9113EI9Z-T use, and what are its dimensions?
The ISL9113EI9Z-T uses a 6-bump WLCSP package (RoHS-compliant, SnAgCu e1 solder balls) measuring 0.800mm × 1.360mm with 0.4mm pitch, per Package Outline Drawing W3x2.6 on page 15 of the FN8313 datasheet. It has no exposed thermal pad.
How does the ISL9113EI9Z-T manage efficiency at light loads?
The ISL9113EI9Z-T enters skip mode after eight consecutive zero-inductor-current detections, reducing quiescent current to 20µA (typical) while maintaining regulation. This behavior is detailed in the "Skip Mode Operation" section (page 7) and confirmed by Figure 9 ("PULSE SKIP MODE WAVEFORM") on page 10 of the datasheet.
