LM3204 - Step-Down DC-DC Converter

Description

The LM3204 is a DC-DC converter optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion cell.

It steps down an input voltage of 2.7V to 5.5V to an adjustable output voltage of 0.8V to 3.6V.

Features

  • 1.
  • 2 2MHz (typ. ) PWM Switching Frequency.
  • Operates from a single Li-Ion cell (2.7V to 5.5V).
  • Adjustable Output Voltage (0.8V to 3.6V).
  • Fast Turn on time when Enabled (50µs Typ. ), 3GPP Compliant.
  • 300mA Maximum load capability (PWM mode).
  • 500mA Maximum load capability (Bypass mode).
  • PWM, Forced and Automatic Bypass Mode.
  • High Efficiency (96% Typ. at 3.6VIN, 3.2VOUT at 120mA).
  • 10-pin micro SMD Package.
  • Current.
