www.ti.com SNVS351C – JUNE 2005 – REVISED APRIL 2013 LM3204 Miniature, Adjustable, Step-Down DC-DC Converter with Bypass Mode for RF
Power Amplifiers
Check for Samples: LM3204 FEATURES 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. The output voltage is set using an analog
input ( VCON) for optimizing efficiency of the RF PA at
various power levels. 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 (50Вµs 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 DSBGA Package
Current Overload Protection …
