LMZ34202 SIMPLE SWITCHER® Power Module

Texas Instruments offers its LMZ34202 SIMPLE SWITCHER, 4.5 V to 42 V, 2 A, step-down voltage regulator

Image of Texas Instruments' LMZ34202 SIMPLE SWITCHER® Power ModuleTexas Instruments' LMZ34202 SIMPLE SWITCHER power module is an easy-to-use, integrated power supply that combines a 2 A, DC-DC converter with a shielded inductor and passives into a low-profile, QFN package. This total power solution allows as few as three external components while maintaining an ability to adjust key parameters to meet specific design requirements.

The QFN package is easy to solder to a printed circuit board, allows reflow profiles up to 260°C, and has excellent power dissipation capability. The LMZ34202 offers flexibility with many features and is ideal for powering a wide range of devices and systems.

Features

  • Complete integrated power solution allows small footprint, low-profile design
  • 10 mm x 10 mm x 4.3 mm package
  • Wide-output voltage adjust (2.5 V to 7.5 V)
  • Adjustable switching frequency (200 kHz to 1 MHz)
  • Synchronizes to an external clock
  • Automatic PFM mode for light load efficiency
  • Adjustable soft-start time
  • Output voltage sequencing and tracking
  • Power good output
  • Programmable undervoltage lockout (UVLO)
  • Over-temperature thermal shutdown protection
  • Over-current protection (hiccup mode)
  • Pre-bias output start-up
  • Operating temperature range: -40°C to 105°C
  • Enhanced thermal performance: 14°C/W
  • Meets EN55022 class B emissions
  • Integrated shielded inductor
