What are the key features of LM3205TLX/NOPB?
- 650 mA current-mode PWM buck converter with adjustable 0.8 V to 3.6 V output for RF PA bias supply
- 2.7 V to 5.5 V input range supporting operation from single-cell Li-ion down to 3 V rails
- Miniature 8-ball DSBGA package enabling sub-4 mm x 4 mm total solution size for compact RF modules
- RoHS-compliant lead-free design with fast transient response for dynamic PA voltage control
What is LM3205TLX/NOPB used for?
The LM3205TLX/NOPB is specifically optimized for powering RF power amplifiers in cellular handsets, WLAN modules, and Bluetooth transceivers where dynamic voltage scaling of the PA supply improves power efficiency at backed-off output power levels. Its 650 mA output current and fast load transient response support burst-mode RF transmitters that require PA voltage changes within microseconds between time slots. It is also used in portable test equipment and IoT wireless nodes requiring a compact, low-noise DC-DC converter from a lithium-ion battery.

Frequently Asked Questions
What output voltage range and current does the LM3205TLX/NOPB support for RF power amplifier designs?
The LM3205TLX/NOPB provides an adjustable output voltage from 0.8 V to 3.6 V at up to 650 mA continuous output current. This range covers the typical PA supply voltage of 1.8 V to 3.4 V used in 2G, 3G, and WLAN power amplifiers, allowing dynamic voltage scaling to optimize transmitter efficiency across different output power levels.
What input voltage range makes the LM3205TLX/NOPB compatible with lithium-ion battery-powered designs?
The LM3205TLX/NOPB accepts input voltages from 2.7 V to 5.5 V, which covers the discharge range of a single-cell lithium-ion battery (3.0 V to 4.2 V) and standard 3.3 V or 5 V regulated rails. This makes it directly operable from a Li-ion cell without a pre-regulator, extending battery run time in mobile RF devices.
How does the 8-ball DSBGA package of the LM3205TLX/NOPB benefit RF module layout?
The 8-ball DSBGA package measures approximately 1.59 mm x 1.96 mm with a 0.5 mm ball pitch, giving a PCB footprint under 4 mm². Placing the converter directly adjacent to the RF PA die reduces supply trace inductance to under 1 nH, minimizing voltage ripple and switching noise coupling into the PA output at frequencies up to 2.4 GHz.
When is the LM3205TLX/NOPB a better choice than an LDO for RF PA power supply in a handset?
Use the LM3205TLX/NOPB instead of an LDO when the input-to-output voltage drop exceeds 0.5 V, as the buck converter achieves efficiency above 85% while an LDO would dissipate the excess voltage as heat with efficiency below 70% at 650 mA. For a 3.7 V battery powering a 1.8 V PA, the LM3205 saves roughly 400 mW of thermal dissipation, directly extending handset talk time.
