TPS62751

The TPS62751 device is a highly efficient synchronous step down dc-dc converter optimized for USB powered portable applications. It can provide up to 1300mA average input current and is ideal for applications connected to a USB host.

Features of the TPS62751 are:(1)efficiency > 90% at nominal operating conditions;(2)programmable average input current limits for USB applications;(3)stable output voltage for load transients to minimize overshoot at load step response;(4)hot plug and reverse current protection;(5)forced PWM for noise sensitive applications;(6)VIN range from 2.9V to 6V;(7)adjustable VOUT From 0.8V to 0.85*VIN;(8)softstart for inrush current prevention;(9)2.25 MHz fixed frequency operation;(10)short cicruit and thermal shutdown protection;(11)available in a 2.5 * 2.5 10 pin SON package.

The absolute maximum ratings of the TPS62751 can be summarized as:(1):the parameter is input voltage range VIN, AVIN,the value is -0.3 to 7,the unit is V;(2):the parameter is voltage range at EN, H/L, FB,the value is -0.3 to VIN +0.3, 7,the unit is V;(3):the parameter is voltage on L, ILim_U, ILim_L,the value is -0.3 to 7,the unit is V;(4):the parameter is peak output current,the value is internally limited;(5):the symbol is Tj,the parameter is maximum operating junction temperature,the value is -40 to 125,the unit is ;(6):the symbol is Tstg,the parameter is storage temperature range,the value is -65 to 150,the unit is ;(7):the parameter is ESD rating HBM human-body model,the value is 4,the unit is kV;(8):the parameter is ESD rating CDM charge device model,the value is 1.5,the unit is kV;(9):the parameter is ESD rating machine model,the value is 200,the unit is V.
