TPP36208 36-V Input, 2-A Synchronous Step-Down Voltage Regulator

Description 

The TPP36208 is a simple, easy-to-use, 2-A output,  synchronous, step-down, switch-mode converter with  internal power MOSFETs.  

The TPP36208 integrates low-RDS(ON) power  transistors in the TSOT23-6 package with internal  soft-start, compensation, and protection features.  

TPP36208 offers a very compact solution to achieve  a 2-A continuous output current over a wide input  supply range, with excellent load and line regulation. TPP36208 has different versions of switching  frequency at 500-kHz and 2.2-MHz, also supports  light load PSM to save quiescent current and forcedPWM mode to maintain fixed switching frequency.  

The device is available in the 6-pin TSOT23-6  package with the support of a wide operation ambient  temperature range from −40 °C to 125 °C.
