SC4501 Datasheet 2mhz Step-up Switching Regulator

Manufacturer: SEMTECH

Overview: SC4501 2Amp, 2MHz Step-Up Switching Regulator with Soft-Start POWER.

General Description

The SC4501 is a high-frequency current-mode step-up switching regulator with an integrated 2A power transistor.

Its high switching frequency (programmable up to 2MHz) allows the use of tiny surface-mount external passive components.

Programmable soft-start eliminates high inrush current during start-up.

Key Features

  • u u u u u u u u u Low saturation voltage switch: 220mV at 2A Constant switching frequency current-mode control Programmable switching frequency up to 2MHz Soft-Start function Input voltage range from 1.4V to 16V Output voltage up to 32V Low shutdown current Adjustable undervoltage lockout threshold Small low-profile thermally enhanced packages The operating frequency of the SC4501 can be set with an external resistor. The ability to set the operating frequency gives the SC4501 design flexibilit.
