LM3477AMM/NOPB TI PWM Controller | 8-VSSOP | 2.97V-5.5V, 1A

Product Overview

The LM3477AMM/NOPB is a high-performance PWM (Pulse Width Modulation) controller from Texas Instruments, designed for step-down (buck) DC-DC converter applications. It operates over a wide input voltage range of 2.97V to 5.5V and can deliver output currents up to 1A. The device is housed in a compact 8-pin VSSOP package, making it ideal for space-constrained designs. With its high switching frequency (up to 1MHz), the LM3477AMM/NOPB enables the use of small external components, reducing overall solution size and cost.
