Product details
Overview
OM13576,598 from NXP Semiconductors is a 3.0 MHz, 500 mA step-up DC-DC converter in WLCSP9 package, delivering fixed 5.0 V output from 2.5–5.25 V input. It features ±3% output voltage accuracy over full load/temperature range, 94% peak efficiency, and integrated soft-start with true load disconnect. Designed for NFC terminals and smartphones requiring compact, high-efficiency power conversion.
For engineers reviewing the OM13576,598 datasheet, OM13576,598 pinout, OM13576,598 application, or OM13576,598 equivalent, this page delivers verified technical context, validated pin functions, confirmed operating modes (Boost, Pass-Through, Total Disconnect), real-world layout constraints, and precise alternative selection guidance - all grounded in NXP's official PCA9410/9410A product data sheet Rev. 1 (2016).
Technical Context
The OM13576,598 implements a current-mode controller with synchronous rectification, enabling stable regulation at 3.0 MHz switching frequency using ≤1 µH inductors. Its dual-mode EN logic supports both forced Pass-Through (PCA9410A behavior) and total input-output disconnect (PCA9410 behavior), determined by top-side marking and internal configuration.
It integrates pre-charge inrush limiting, overcurrent protection with 20 ms fault recovery, thermal shutdown at 150 °C with 20 °C hysteresis, and UVLO with 2.1 V rising threshold and 70–120 mV hysteresis. The device maintains ±3% VOUT accuracy across –40 °C to +85 °C ambient and supports VIN ≥ VOUT operation without external diode loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V with ±3% accuracy over full load, input, and temperature range - ensures stable USB-compliant rail for NFC ICs and baseband processors. |
| Switching Frequency | 3.0 MHz (2.91–3.09 MHz typ.) - enables use of ultra-small 0603 inductors (e.g., ASMPH-0603-1R0M-T) and reduces output ripple without increasing ESR sensitivity. |
| Max Output Current | 500 mA continuous - sufficient to power dual-mode NFC transceivers (e.g., PN548) and RF front-end modules under peak transmit conditions. |
| Efficiency | Up to 94% at mid-load - extends battery runtime in space-constrained portable devices where thermal dissipation is limited. |
| Input Voltage Range | 2.5 V to 5.25 V - compatible with single-cell Li-ion (3.0–4.2 V), Li-polymer, and boosted coin-cell sources. |
| Enable Logic | EN HIGH = Boost Mode; EN LOW = PCA9410A-style forced Pass-Through (VIN directly coupled to VOUT) - eliminates body-diode drop in battery-backup paths. |
| Thermal Protection | Shuts down at 150 °C junction temperature with 20 °C hysteresis - prevents permanent damage during sustained high-current operation in sealed enclosures. |
Pinout & Package
OM13576,598 uses a Wafer-Level Chip-Size Package (WLCSP9) with 1.24 × 1.24 × 0.525 mm body, 0.4 mm pitch, and 9 solder bumps. The package supports fine-pitch PCB assembly and minimizes parasitic inductance for high-frequency switching.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (A1, A2) | Regulated output voltage node | Direct connection point for output capacitor (≥3.0 µF at 5 V); shortest possible trace to PGND required for loop stability and ripple suppression. |
| VIN (A3) | Main input power supply | Accepts 2.5–5.25 V battery source; connects to input decoupling cap (≥2.2 µF) placed adjacent to pin to suppress transients. |
| SW (B1, B2) | Internal switch node | Drives external inductor; requires low-inductance routing to minimize EMI and switching losses at 3 MHz. |
| EN (B3) | Enable control input | Active-HIGH enable; LOW forces Pass-Through mode (VIN → VOUT) in PCA9410A variant - must be held HIGH ≥500 µs for reliable startup. |
| PGND (C1, C2) | Power ground return | Primary return path for inductor current and output capacitor; shortest possible connection to COUT negative terminal essential for noise control. |
| AGND (C3) | Analog reference ground | Signal reference for internal bandgap and error amplifier; must connect to PGND at single-point star ground to avoid ground bounce errors. |
Key Features
| Feature | Design Value |
|---|---|
| Pass-Through Mode | Enables zero-drop VIN-to-VOUT conduction when EN = LOW (PCA9410A behavior), eliminating forward voltage loss of discrete diodes in backup power paths. |
| Soft-Start with Pre-Charge | Two-stage startup (inrush control + boost ramp) limits inrush current and prevents output voltage overshoot during cold start or battery insertion. |
| Total Input-Output Disconnect | When disabled, OM13576,598 fully isolates VIN from VOUT - critical for preventing leakage into powered-down subsystems in always-on mobile architectures. |
| Integrated Overcurrent Protection | Monitors PMOS current and shuts down within microseconds on overcurrent; auto-restarts after 20 ms timeout - protects against shorted loads without external circuitry. |
| High-Frequency Operation | 3.0 MHz switching allows use of 1 µH inductors in 0603 footprint, reducing solution size by >40% versus 1 MHz boost converters while maintaining <20 mV p-p ripple. |
Applications
| Smartphone Power Management | NFC Terminal Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DC-DC boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61291DRVR | Fixed 5.0 V output, 1.2 MHz switching, 400 mA max, 2.5–5.5 V input, 1.2 mm × 1.6 mm DSBGA9 package | Lacks forced Pass-Through mode; no EN-controlled VIN–VOUT coupling - requires external diode for backup path | Select when board space allows larger inductor and lower EMI is prioritized over minimal footprint. |
| MAX17222ELT+T | Adjustable output (0.6–5.5 V), 2.5 MHz switching, 500 mA, 0.7–5.5 V input, 1.22 mm × 0.83 mm WLP-6 package | Requires external feedback resistors; no integrated Pass-Through or total disconnect - needs additional MOSFET for isolation | Select when output voltage flexibility (e.g., 3.3 V for MCU core) outweighs need for fixed 5 V and integrated control features. |
Compared with TPS61291DRVR and MAX17222ELT+T, OM13576,598 uniquely combines fixed 5 V regulation, 3 MHz operation in sub-1.3 mm² WLCSP9, and dual-mode EN control - enabling smaller total solution size, lower component count, and simpler firmware control in NFC and smartphone power rails.

FAQ
What is the exact function of the EN pin on OM13576,598?
The EN pin on OM13576,598 controls operational mode: HIGH enables standard boost regulation (5.0 V output); LOW forces Pass-Through mode, directly connecting VIN to VOUT with minimal voltage drop. This behavior matches the PCA9410A variant. OM13576,598 must be held HIGH for ≥500 µs at startup to initialize correctly before transitioning to Pass-Through.
Does OM13576,598 support automatic Pass-Through mode when input voltage exceeds 5 V?
Yes. OM13576,598 automatically enters Pass-Through mode whenever VIN rises above the 5.0 V output target, providing a low-impedance path without requiring EN pin intervention. This occurs during battery charging or USB-powered operation, ensuring seamless voltage handover without output interruption.
What is the recommended inductor value and package for OM13576,598?
NXP specifies a 1 µH inductor as optimal for OM13576,598, with Abracon ASMPH-0603-1R0M-T (0603 package, 800 mA saturation current) explicitly recommended. Using this part ensures stable 500 mA operation at 3.0 MHz while maintaining <20 mV output ripple and minimal board area.
How does OM13576,598 handle overcurrent events?
OM13576,598 detects overcurrent via its integrated PMOS switch and immediately disables both high- and low-side FETs. After a fixed 20 ms fault timeout, it restarts from the pre-charge phase. This autonomous protection eliminates need for external current-sense resistors or fault-handling firmware in the host system.
Is OM13576,598 compatible with lead-free reflow processes?
Yes. OM13576,598 uses a lead-free WLCSP9 package with SAC105N solder balls and complies with J-STD-020D Class 3 moisture sensitivity. Its peak reflow temperature requirement is 260 °C, matching standard lead-free profiles - no special thermal derating or process adjustments are needed.
