Linear Technology offers two new buck regulators that operate from a wide input voltage range (3.6V to 36V) and take so little space that they easily solve many difficult power supply problems. The LT®1936 and LT1933 are perfect for applications with disparate power inputs or wide range input power supplies such as automotive batteries, 24V industrial supplies, 5V logic supplies and various wall adapters. Both parts are monolithic current mode PWM regulators which provide excellent line and load regulation and dynamic response. They operate at a 500kHz switching frequency, enabling the use of small, low cost inductors and ceramic capacitors, resulting in low, predictable output ripple.
This document introduces two new buck regulators, the LT1936 and LT1933, which operate from a wide input voltage range of 3.6V to 36V. These monolithic current mode PWM regulators are designed for applications with disparate power inputs or wide-range supplies, such as automotive batteries and industrial sources. They feature small package sizes (MSOP and ThinSOT) and offer options for internal or external compensation.
