The LP6460A contains an independent 600KHz constant frequency, current mode, PWM step-down converters. The converter integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The LP6460A is ideal for powering portable equipment that runs from a 2cell Lithium-Ion (Li+) battery. The converter can supply 2000mA of load current from a 3.5V to 16V input voltage. The output voltage can be regulated as low as 0.6V. The LP6460A is available in a SOT23-6 package and is rated over the -40℃ to 85℃ temperature range.

LN5016 is a current mode monolithic buck switching regulator. Operating with an input range of 4.5V~40V, the LN5016 delivers 1.5A of continuous output current with two integrated N-Channel MOSFETs. The internal synchronous power switches provide high efficiency without the use of an external Schottky diode. At light loads, the regulator operates in low frequency to maintain high efficiency and low output ripple. Current mode control provides tight load transient response and cycle-by-cycle current limit. The LN5016 guarantees robustness with short-circuit protection, thermal protection, current run-away protection, and input under voltage lockout. The LN5016 is available in 6-pin SOT23-6L package, which provides a compact solution with minimal external components
