LM3241 - Step-Down DC-DC Converter

Description

The LM3241 is a DC-DC converter optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion cell.

The device can also be used in many other applications.

The device steps down an input voltage from 2.7 V to 5.5 V to an adjustable output voltage from 0.6 V to 3.4 V.

Features

  • 1 6-MHz (typ. ) PWM Switching Frequency.
  • Operates from a Single Li-Ion Cell (2.7 V to 5.5 V).
  • Adjustable Output Voltage (0.6 V to 3.4 V).
  • 750-mA Maximum Load Capability.
  • High Efficiency (95% typ. at 3.9 VIN, 3.3 VOUT at 500 mA).
  • Automatic Eco-mode™ and PWM Mode Change.
  • 6-Bump DSBGA Package.
  • Current Overload Protection.
  • Thermal Overload Protection.
  • Soft Start Function.
  • CIN and COUT are 0402 (1005) Ca.
