LM3262 DSBGA Evaluation Board
1 Introduction
The LM3262 evaluation board is a working demonstration of an adjustable step-down DC-DC converter
optimized for powering RF power amplifiers (PAs) from a single Lithium-Ion cell. Output voltage is set
using a VCON analog input for controlling power levels and efficiency of the RF PA.
2 Operating Conditions
The device will operate under the following conditions:
• V
IN
range: 2.5V to 5.5V
• V
OUT
range: 0.4V to 3.6V
• VCON range: 0.16V to 1.44V
• V
OUT
equation: V
OUT
= 2.5 x VCON
• I
OUT
range: 0 mA to 800 mA
3 Package
The LM3262 is available in a 9-bump (0.4 mm pitch) lead-free DSBGA (1.355 mm x 1.48 mm x 0.6 mm)
package. The total solution size of the LM3262 and external components is ≈ 7.1 mm
