SC451 [Portable IMVP-IV™ and IMVP-IV+™ Single Phase Power Supply Controller ] Semtech
Semtech Corporation

Description
The SC451 PowerStep IV™ IC is a single chip high-performance Hysteretic PWM controller. With its integrated SmartDriver™, it powers advanced IMVP-IV™ and IMVP4+™ processors. The SC451 features extended Intel Mobile Voltage Positioning (IMVP™) to increase battery life by reducing the voltage at the processor when it is heavily loaded. It directly supports Intel’s SpeedStep® processors for even longer battery life. The SC451 fully supports the Intel® Geyserville-III core voltage specification.

SC4510 [High Performance Synchronous Buck Controller With Reference Tracking ]

other parts : SC4510ITSTR  SC4510ITSTRT 

Semtech
Semtech Corporation

Description
The SC4510 can be configured as a synchronous buck convertor capable of sourcing and sinking current from load without losing output regulation. The output can be set to track an internal reference or an external voltage. The actual reference used by the error amplifier is buffered and brought out as a reference. It is the ideal choice for externally referenced or tracking buck convertors such as those for DDR memory applications.

Features
◆ Synchronous buck operation with current sink or
   source without loss of regulation
◆ Output can track internal or external reference
◆ Buffered reference output from external reference
◆ Combi-Sense mode lossless current sensing
◆ 2.5V to 16V operation with 4.75V minimum VCC
◆ Direct drive for high side N-channel MOSFETs with
   diode and capacitor bootstrap
◆ Undervoltage lockout, Soft Start, Enable and Power
   Good functions
◆ Fast transient response with external compensation
◆ Current mode control with transconductance error
   amplifier
◆ Programmable oscillator frequency with external sync

Applications
◆ Externally referenced buck convertors
◆ DDR memory terminators
◆ Point of use power supplies

SC4519 [600kHz, 3A Step-Down Switching Regulator ]

other parts : SC4519EVB  SC4519STRT 

Semtech
Semtech Corporation

Description
The SC4519 is a current mode switching regulator with an integrated switch, operating at 600kHz with separate sync and enable functions. The integrated switch allows for cost effective low power solutions (peak switch current 3 amps). The sync function allows customers to synchronize to a faster clock in order to avoid frequency beating in noise sensitive applications. High frequency of operation allows for very small passive components. Current mode operation allows for fast dynamic response and instantaneous duty cycle adjustment as the input varies (ideal for CPE applications where the input is a wall plug power).

Features
♦ Integrated 3 Amp switch
♦ 600kHz frequency of operation
♦ Current mode controller
♦ Synchronizable to higher frequency up to 1.2MHz
♦ 6µA low shutdown current
♦ SOIC-8L-EDP Lead-free package. This product is fully WEEE and RoHS compliant

Applications
♦ XDSL modems
♦ CPE equipment
♦ DC-DC point of load applications
♦ Portable equipment
