LM3262TME/NOPB Description

LM3262TME/NOPB is a type of DC-DC converter optimized for powering RF power amplifiers (PAs) from a single lithium-ion cell. It is able to operate in five modes. In pulse width modulation (PWM) mode the device operates at a fixed frequency of 6 MHz (typical), which minimizes RF interference at medium-to-low loads. At light load, the device enters into ECO mode automatically and operates with reduced switching frequency. In ECO mode, the quiescent current is reduced and extends the battery life. Shutdown mode turns the device off and reduces battery consumption to 0.1 μA (typical). At low-battery condition, bypass mode reduces the voltage dropout to less than 50 mV (typical). The device also features a sleep mode.
