7.1 Overview

The TLVM13630 is an easy-to-use, synchronous buck, DC-DC power module that operates from a 3-V to 36-V supply voltage. The device is intended for step-down conversions from 5-V, 12-V, and 24-V supply rails. With an integrated power controller, inductor, and MOSFETs, the TLVM13630 delivers up to 3-A DC load current, with high efficiency and ultra-low input quiescent current, in a very small solution size. Although designed for simple implementation, this device offers flexibility to optimize its usage according to the target application. Control-loop compensation is not required, reducing design time and external component count.

With a programmable switching frequency from 200 kHz to 2.2 MHz using its RT pin, the TLVM13630 incorporates specific features to improve EMI performance in noise-sensitive applications:

  • An optimized package and pinout design enables a shielded switch-node layout that mitigates radiated EMI
  • Parallel input and output paths with symmetrical capacitor layouts minimize parasitic inductance, switch-voltage ringing, and radiated field coupling
  • Clock synchronization and FPWM mode enable constant switching frequency across the load current range
  • Integrated power MOSFETs with enhanced gate drive control enable low-noise PWM switching
  • Adjustable switch-node slew rate, which allows optimization of EMI at higher frequency harmonics

The TLVM13630 module also includes inherent protection features for robust system requirements:

  • An open-drain PGOOD indicator for power-rail sequencing and fault reporting
  • Precision enable input with hysteresis, providing
    • Programmable line undervoltage lockout (UVLO)
    • Remote ON/OFF capability
  • Internally fixed output-voltage soft start with monotonic startup into prebiased loads
  • Hiccup-mode overcurrent protection with cycle-by-cycle peak and valley current limits
  • Thermal shutdown with automatic recovery.

These features enable a flexible and easy-to-use platform for a wide range of applications. The pin arrangement is designed for simple layout, requiring few external components. See Section 10 for layout example.
