The LTC3412A is a high efficiency monolithic synchronous, step-down DC/DC converter utilizing a constant frequency, current mode architecture. It operates from an input voltage range of 2.25V to 5.5V and provides a regulated output voltage from 0.8V to 5V while delivering up to 3A of output current. The internal synchronous power switch with 77m? on-resistance increases efficiency and eliminates the need for an external Schottky diode. Switching frequency is set by an external resistor or can be synchronized to an external clock. 100% duty cycle provides low dropout operation extending battery life in portable systems. OPTI-LOOP? compensation allows the transient response to be optimized over a wide range of loads and output capacitors. The LTC3412A can be configured for either Burst Mode operation or forced continuous operation. Forced continuous operation reduces noise and RF interference while Burst Mode operation provides high efficiency by reducing gate charge losses at light loads. In Burst Mode operation, external control of the burst clamp level allows the output voltage ripple to be adjusted according to the application requirements.APPLICATIONS Point-of-Load Regulation Notebook Computers Portable Instruments Distributed Power Systems

The ADP122 / ADP123 are low quiescent current, low dropoutlinear regulators. They are designed to operate from an inputvoltage between 2.3 V and 5.5 V and to provide up to 300 mA of output current. The low 85 mV dropout voltage at a 300 mA loadimproves efficiency and allows operation over a wide inputvoltage range.The low 170 μA of quiescent current at full load makes the ADP122ideal for battery-operated portable equipment.The ADP122 is capable of 31 fixed output voltages from 1.75 Vto 3.3 V. The ADP123 is the adjustable version of the device andallows the output voltage to be set between 0.8 V and 5.0 V by an external voltage divider.The ADP122 / ADP123 are specifically designed for stable operationwith tiny 1 μF ceramic input and output capacitors to meet therequirements of high performance, space constrained applications.The ADP122 / ADP123 have an internal soft start that gives aconstant start-up time of 350 μs. Short-circuit protection andthermal overload protection circuits prevent damage in adverse conditions. The ADP122 / ADP123 are available in a tiny, 5-leadTSOT package and 6-lead LFCSP package for the smallestfootprint solution to meet a variety of portable applications.APPLICATIONS Digital camera and audio devices Portable and battery-powered equipment Automatic meter reading (AMR) meters GPS and location management units Medical instrumentation Point-of-sale equipment

The LT3753 is a current mode PWM controller optimized for an active clamp forward converter topology, allowing up to 100V input operation.A programmable volt-second clamp allows primary switch duty cycles above 50% for high switch, transformer and rectifier utilization. Active clamp control reduces switch voltage stress and increases efficiency. A synchronous output is available for controlling secondary side synchronous rectification.The LT3753 is available in a 38-lead plastic TSSOP package with missing pins for high voltage spacings.Applications Industrial, Automotive and Military Systems 48V Telecommunication Isolated Power Supplies

The LTC3225/LTC3225-1 are programmable supercapacitor chargers designed to charge two supercapacitors in series to a selectable fixed output voltage (4.8V/5.3V for the LTC3225 and 4V/4.5V for the LTC3225-1) from input supplies as low as 2.8V to 5.5V. Automatic cell balancing prevents overvoltage damage to either supercapacitor. No balancing resistors are required. Low input noise, low quiescent current and low external parts count (one flying capacitor, one bypass capacitor at VIN and one programming resistor) make the LTC3225/LTC3225-1 ideally suited for small battery-powered applications. Charge current level is programmed with an external resistor. When the input supply is removed, the LTC3225/LTC3225-1 automatically enter a low current state, drawing less than 1?A from the supercapacitors. The LTC3225/LTC3225-1 are available in a 10-lead 2mm ? 3mm DFN package.Applications Current Limited Applications with High Peak Power Loads (LED Flash, PCMCIA Tx Bursts, HDD Bursts, GPRS/GSM Transmitter) Backup Supplies
