Product details
Overview
ISL9113ER7Z-T from Renesas (formerly Intersil) is a fixed 5V synchronous boost converter IC optimized for low-input-voltage battery-powered systems. It delivers up to 500mA output from 3.0V input, features 1.8MHz switching frequency, 20µA quiescent current in skip mode, and integrated N- and P-channel MOSFETs with 0.20Ω/0.35Ω RDS(ON). It is used in USB-OTG power rails and portable HDMI interfaces.
For engineers reviewing the ISL9113ER7Z-T datasheet, ISL9113ER7Z-T pinout, ISL9113ER7Z-T application, or ISL9113ER7Z-T equivalent, key selection criteria include its 0.8V–4.7V input range, fixed 5V output accuracy (±1%), 8-lead DFN package with exposed thermal pad, and fault reporting via open-drain FAULT pin.
Technical Context
The ISL9113ER7Z-T implements peak current-mode PWM control with internal compensation and a 1.8MHz oscillator. Its synchronous rectification uses an integrated N-channel (0.20Ω) and P-channel (0.35Ω) MOSFET pair to eliminate external Schottky losses.
It operates in two modes: continuous PWM at medium-to-heavy loads and pulse-skipping mode below ~10mA, reducing quiescent current to 20µA. Fault protection includes undervoltage lockout (0.70V), thermal shutdown (150°C), and output disconnect during shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.8V to 4.7V - supports single-cell Li-ion (2.7–4.2V), three-cell alkaline/NiMH (2.4–4.5V), and ultra-low-voltage start-up down to 2.8V. |
| Output Voltage | Fixed 5.0V ±1% - internally trimmed; no external feedback resistors required; stable across 0–500mA load at VIN ≥ 3.0V. |
| Switching Frequency | 1.8MHz (typical) - enables use of 2.2µH inductors and 4.7µF ceramic capacitors, minimizing solution footprint. |
| Peak Switch Current Limit | 1.3A (typical) - sets maximum inductor current; ensures robust operation under transient overloads and short-circuit conditions. |
| Quiescent Current | 20µA (typical, skip mode) - extends battery life in standby; drops to <1µA in logic-controlled shutdown. |
| Efficiency | Up to 95% at 500mA - achieved via synchronous rectification and low RDS(ON) MOSFETs; >85% maintained down to 1mA load. |
| Operating Temperature | –20°C to +85°C - qualified for consumer and industrial portable applications; junction limit is +125°C. |
Pinout & Package
ISL9113ER7Z-T is housed in an 8-lead 2mm × 2mm DFN package (RoHS-compliant, L8.2x2D) with an exposed thermal pad requiring connection to PGND for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 PGND | Power Ground | Main return path for high-current switch node; must be low-inductance connection to system ground plane. |
| 2 VOUT | Regulated Output | 5V fixed output node; connects to 4.7µF ceramic capacitor and load; provides up to 500mA. |
| 3 NC | No Connection | Unbonded pin; must remain unconnected per datasheet; no routing or copper fill allowed. |
| 4 FAULT | Open-Drain Fault Indicator | Active-low signal indicating UVLO, thermal shutdown, short circuit, or output regulation failure; requires external pull-up. |
| 5 EN | Enable Input | Logic-high (≥1.2V) activates converter; logic-low (<0.35V) disables with <1µA shutdown current and output disconnect. |
| 6 AGND | Analog Ground | Reference for internal error amplifier and feedback circuitry; should be tied to PGND at single point near IC. |
| 7 VBAT | Battery Input | Primary power input (0.8–4.7V); requires 4.7µF ceramic capacitor placed adjacent to pin and PGND. |
| 8 SW | Switching Node | Connection point for inductor; carries high di/dt square-wave voltage; must be routed short and wide to minimize EMI. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous Boost Architecture | Integrated N- and P-channel MOSFETs replace lossy Schottky diode, enabling >90% efficiency at light loads and eliminating reverse leakage. |
| Output Disconnect During Shutdown | Internal P-MOSFET blocks reverse current flow from VOUT to VBAT when EN = LOW, preventing battery drain in system sleep states. |
| Programmable Skip Mode | Automatically engages below ~10mA load, reducing switching losses and holding quiescent current at 20µA for extended battery runtime. |
| Fault Protection Suite | Includes undervoltage lockout (0.70V), thermal shutdown (150°C), and short-circuit detection - all reported via FAULT pin with auto-restart. |
| Internal Soft-Start | Linear ramp-up limits inrush current; achieves 5V output within 1ms (typical) while controlling peak inductor current to 1.3A. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS610992RTER | Fixed 5V output, 1.2MHz switching, 400mA max output, 0.75µA shutdown current, 6-pin WSON package. | Lacks FAULT pin and output disconnect; lower max output current; better suited for ultra-low-IQ wearables vs. USB-OTG power delivery. | Choose for sub-1µA shutdown and space-constrained designs where fault reporting and 500mA are not required. |
| MAX17222ELT+T | Fixed 5V output, 1.2MHz, 500mA, 1.6µA shutdown, 6-pin WLP package; no FAULT pin or thermal shutdown. | No fault reporting or thermal protection; lacks output disconnect; rated for –40°C to +85°C industrial temp range. | Prefer for cost-sensitive industrial sensor nodes needing wider temperature range but tolerating reduced protection features. |

FAQ
What is the minimum input voltage required for the ISL9113ER7Z-T to start up?
The ISL9113ER7Z-T has a guaranteed start-up voltage of 3.0V (typical 2.8V) when EN is asserted at 1.2V. Below this threshold, the device remains in undervoltage lockout until VBAT rises above 0.70V, at which point internal circuitry powers up and begins soft-start sequencing. This ensures reliable boot from partially discharged batteries.
Does the ISL9113ER7Z-T require external feedback resistors to set the output voltage?
No, the ISL9113ER7Z-T does not require external feedback resistors. It is the fixed 5.0V output variant with an internal voltage divider; pins FB and NC are unused. Only the adjustable versions (e.g., ISL9113ERAZ-T) require external R1/R2 resistors connected to the FB pin.
How does the FAULT pin behave during over-temperature events?
When die temperature exceeds 150°C, the ISL9113ER7Z-T asserts the FAULT pin LOW and halts switching. The pin remains LOW until temperature falls to ~125°C (25°C hysteresis), at which point the device automatically resumes operation without requiring an EN toggle or power cycle.
Can the ISL9113ER7Z-T drive a 500mA load continuously at 3.0V input?
Yes, the ISL9113ER7Z-T is specified to deliver 500mA continuously at VBAT = 3.0V and VOUT = 5.0V, with typical efficiency >85%. Thermal performance depends on PCB layout: the exposed pad must be connected to PGND with ≥4 vias to maintain junction temperature within limits under full load.
Is output disconnect active during logic-controlled shutdown of the ISL9113ER7Z-T?
Yes, when EN is pulled LOW, the ISL9113ER7Z-T actively disconnects VOUT from VBAT using its internal P-channel MOSFET. This prevents reverse current flow and battery depletion during system sleep - a critical feature confirmed in the datasheet's "Detailed Description" section on synchronous rectifier operation.
