NXP Semiconductors OM13577,598

Overview

OM13577,598 from NXP Semiconductors is a 3.0 MHz, 500 mA step-up DC-DC converter in WLCSP9 package, delivering a fixed 5.0 V output from 2.5 V–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 OM13577,598 datasheet, OM13577,598 pinout, OM13577,598 application, or OM13577,598 equivalent, this page delivers verified technical context, validated pin functions, confirmed operating modes (Boost, Pass-Through, Total Disconnect), real-world layout constraints for WLCSP9, and precise alternative part comparisons - all grounded in NXP's official PCA9410/9410A product data sheet Rev. 1 (2016).

Technical Context

The OM13577,598 implements a current-mode control architecture with synchronous rectification, enabling stable regulation at 3.0 MHz switching frequency and supporting ≤1 µH inductors. Its dual-mode EN logic distinguishes it from standard boost converters: LOW on EN forces total input-output disconnect (PCA9410 variant) or pass-through mode (PCA9410A variant), while automatic pass-through activates when VIN exceeds 5.0 V.

It integrates thermal shutdown (150 °C trip, 20 °C hysteresis), overcurrent protection with 20 ms fault recovery, and a two-stage soft-start sequence (inrush control + boost ramp) to limit inrush current and prevent output voltage dip. The device uses separate AGND and PGND pins with single-point connection guidance to minimize noise coupling.

Key Specifications

Pinout & Package

OM13577,598 is housed in a Wafer-Level Chip-Size Package (WLCSP9) measuring 1.24 mm × 1.24 mm × 0.525 mm with 0.4 mm bump pitch. The package uses SAC105N solder balls and requires lead-free reflow per J-STD-020D Class 3 (peak temp 260 °C). Moisture sensitivity level (MSL) compliance must be observed during handling.

FAQ

What is the exact package type and dimensions of OM13577,598?

OM13577,598 uses a Wafer-Level Chip-Size Package (WLCSP9) with dimensions 1.24 mm × 1.24 mm × 0.525 mm and 0.4 mm bump pitch. It contains nine solder bumps arranged in a 3×3 grid (A1–C3), with dual VOUT, dual PGND, and dedicated AGND, VIN, SW, and EN terminals as defined in NXP's PCA9410 datasheet Figure 3.

Does OM13577,598 support automatic pass-through mode, and how does it behave?

Yes, OM13577,598 supports automatic pass-through mode: when VIN exceeds the 5.0 V output target, the device transitions to a low-impedance path (<100 mΩ) from input to output, bypassing the boost circuitry. This occurs without external control and improves efficiency during high-input-voltage conditions - a core feature confirmed in Section 7.1.1 of the PCA9410 datasheet.

What is the enable (EN) pin behavior for OM13577,598, and is it compatible with PCA9410 or PCA9410A?

OM13577,598 implements the PCA9410 variant's EN behavior: EN LOW forces total input-output disconnect (no current path), while EN HIGH enables boost operation. This is distinct from PCA9410A, which enters forced pass-through on EN LOW. The top-side marking "P10" on OM13577,598 confirms PCA9410 functionality per Table 1 of the datasheet.

What are the recommended external components for OM13577,598, and why are they critical?

OM13577,598 requires a 1 µH inductor (e.g., Abracon ASMPH-0603-1R0M-T), ≥2.2 µF input capacitor (e.g., TDK C1608X5R0J226M080AC), and ≥3.0 µF output capacitor (derated at 5 V). These values ensure stable loop control, minimize ripple (<2 mV p-p), prevent inrush faults, and maintain efficiency - all validated in Sections 11.6–11.8 and Figures 16–17 of the PCA9410 datasheet.

How does OM13577,598 handle thermal overload, and what is its safe operating temperature range?

OM13577,598 incorporates thermal shutdown that disables the PMOS switch at 150 °C junction temperature, with 20 °C hysteresis for restart. Its specified ambient operating range is −40 °C to +85 °C, and junction temperature must remain ≤125 °C under normal operation per Table 7. Layout guidelines (Section 11.9) emphasize short, wide traces to PGND/VOUT to sustain thermal performance in WLCSP9 form factor.
