LM26420 Description

Short technical summary and product information.

The LM26420 from Texas Instruments is a monolithic, high-efficiency dual PWM step-down DC/DC converter. This device is designed to drive two 2-A loads, utilizing internal PMOS and NMOS switches for optimal power density.

Key electrical specifications include an input voltage range of 3 V to 5.5 V and an output voltage range from 0.8 V to 4.5 V. It offers an output current of 2 A per regulator. The device operates at high switching frequencies, with options for 2.2 MHz (LM26420X) or 0.55 MHz (LM26420Y). Efficiencies up to 93% are achievable.

Features include internal soft start, independent power good and precision enable for each output, current mode PWM operation, thermal shutdown, and overvoltage protection. It supports start-up into prebiased output loads and regulators operate 180° out of phase. The device is compliant with CISPR25 Class 5 conducted emissions.

Available in HTSSOP (20) and WQFN (16) packages, the LM26420 is suitable for applications such as local 5V to Vcore of FPGAs, core power in HDDs and set-top boxes, USB powered devices, and powering core and I/O voltages for CPUs and ASICs.
