LM26420 - High Frequency 2.0A Load - Step-Down DC-DC Regulator

Description

The LM26420 regulator is a monolithic, high frequency, dual PWM step-down DC/DC converter in a 16 Pin LLP and a 20 Pin eTSSOP package.

It provides all the active functions to provide local DC/DC conversion with fast transient response and accurate regulation in the smallest possible PCB area.

Features

  • include internal soft-start circuitry to reduce inrush current, pulse-by-pulse current limit, thermal shutdown, power good indicators, precision enables, and output over-voltage protection. Features.
  • Input voltage range of 3.0V to 5.5V Output voltage range of 0.8V to 4.5V 2.0A output current per output High Switching Frequencies 2.2MHz (LM26420X) 0.55MHz (LM26420Y) 75mΩ PMOS switch 50mΩ NMOS switch 0.8V, 1.

LM26420 Dual 2.0A, High Frequency Step-Down DC-DC Regulator March 24, 2009 LM26420 Dual 2.0A, High Frequency Synchronous Step-Down DCDC Regulator www.datasheet4u.com General Description The LM26420 regulator is a monolithic, high frequency, dual PWM step-down DC/DC converter in a 16 Pin LLP and a 20 Pin eTSSOP package. It provides all the active functions to provide local DC/DC conversion with fast transient response and accurate regulation in the smallest possible PCB area. With a minimum of external components, the LM26420 is easy to use. The ability to drive two 2.0A loads with an internal 75 mΩ PMOS top switch and an internal 50 mΩ NMOS bottom switch using state-of-the-art 0.5 µm BiCMOS technology results in the best power density available.
