The SC1109 is a synchronous voltage mode controller (switching section) designed by Semtech, which integrates 2 low-dropout linear regulator controllers. The voltage mode controller provides the power supply for the system AGTL bus. The 1.8V and 2.5V linear controllers power the Chipset and clock circuitry.

SC1103 is a cost-effective single-ended DC/DC power supply controller with temperature compensated voltage reference, triangle wave oscillator, current limit comparator, frequency shift over-current protection and an internally compensated error amplifier.

The SC1102 is a low-cost, full featured, synchronous voltage-mode controller designed for use in single ended power supply applications where efficiency is of primary concern. Synchronous operation allows for the elimination of heat sinks in many applications. The SC1102 is ideal for implementing DC/DC converters needed to power advanced microprocessors in low cost systems, or in distributed power applications where efficiency is important. Internal level-shift, high- side drive circuitry, and preset shoot-thru control, al- lows the use of inexpensive N-channel power switches. SC1102 features include temperature compensated voltage reference, triangle wave oscillator and current sense comparator circuitry. Power good signaling, shutdown, and over voltage protection are also pro- vided. The SC1102 operates at a fixed 200kHz, providing an optimum compromise between efficiency, external component size, and cost.

The SC1101 is a low cost voltage mode PWM controller from SEMTECH CORP. It features low cost, small size, high conversion efficiency.

LP2951A is an improved version of the LP2951 and features tighter tolerance on the output voltage and reference voltage specifications. Both the LP2951 and LP2951A feature 150mA output current capability. The LP2951 series of low power voltage regulators have low quiescent current and low dropout voltage. The quiescent current increases minimally during dropout conditions thereby extending battery life. Available in the eight lead SOIC package, the LP2951 series includes features such as shutdown and low output voltage detect (typically due to low battery conditions). This function may also be used as a power on reset function when triggered by CMOS or TTL inputs. The circuit can be used as a fixed voltage 5 volt regulator or adjusted between 1.24 volts and 29 volts using external resistor pairs.
