LT1501 - Adaptive-Frequency Current Mode Switching Regulators

Download the LT1501 datasheet PDF. This datasheet also covers the LT1 variant, as both devices belong to the same adaptive-frequency current mode switching regulators family and are provided as variant models within a single manufacturer datasheet.

Description

The LT®1500 is an adaptive-frequency current mode stepup switching regulator with an internal power switch that is rated up to 700mA.

In contrast to pulse skipping switching regulators, the LT1500 uses a current mode topology that provides lower noise operation and improved efficiency.

LT1500/LT1501 Adaptive-Frequency Current Mode Switching Regulators FEATURES s DESCRIPTION The LT®1500 is an adaptive-frequency current mode stepup switching regulator with an internal power switch that is rated up to 700mA. In contrast to pulse skipping switching regulators, the LT1500 uses a current mode topology that provides lower noise operation and improved efficiency. Only at very light loads is Burst ModeTM activated to give high efficiency and micropower operation. High switching frequency (up to 500kHz) allows very small inductors to be used, along with ceramic capacitors if desired. The LT1500 operates with input voltages from 1.8V to 15V and has only 200µA operating current dropping to 8µA in shutdown. A low-battery comparator is included which stays alive in shutdown.
