SC4501 - 2MHz Step-Up Switching Regulator

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.

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.

SC4501 2Amp, 2MHz Step-Up Switching Regulator with Soft-Start POWER MANAGEMENT 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. The internal switch is rated at 32V making the converter suitable for high voltage applications such as Boost, SEPIC and Flyback. www.DataSheet4U.com 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.
