SNVS875O – AUGUST 2012 – REVISED DECEMBER 2015 LM3262 6-MHz, 800-mA Miniature, Adjustable, Step-Down DC-DC
Converter With Auto Bypass for RF Power Amplifiers
1 Features 3 Description The LM3262 is a DC-DC converter optimized for
powering RF power amplifiers (PAs) from a single
lithium-ion cell; however, it may be used in many
other applications such as USB-powered portable
applications. The device 2.5-V to 5.5-V input voltage
can be stepped down to an adjustable output voltage
range from 0.4 V to 3.6 V. Output voltage is set using
a VCON analog input which enables improved RFstage PA efficiencies. 1 Operates from a Single Li-Ion Cell (2.5 V to 5.5 V)
6-MHz (Typical) PWM Switching Frequency
Adjustable Output Voltage (0.4 V to 3.6 V)
800-mA Maximum Load Capability (up to 1 A in
Bypass Mode)
High Efficiency (93% Typical at 3.8 VIN, 3.4 VOUT
at 500 mA)
Automatic ECO/PWM/BP Mode Change …
