OCP2576

OCP2576 Simple Switch 3A Step-down Voltage Regulator „ Features „ General Description z Output voltage: 3.3V, 5V, 12V, 15V and adjustable The OCP2576 series of regulators are monolithic IC output versions that provide all the active function for a step-down z Adjustable version output voltage range:1.23V to (buck) switching regulator, capable of driving 3A load 30V±4% max over line and load conditions with excellent line and load regulation. These z Guaranteed 3A output current devices are available in fixed output voltages of z Input voltage up to 36V 3.3V, 5V, 12V, 15V and an adjustable output version. z z z z z Requires only 4 external components 52KHz fixed frequency internal oscillator TTL shutdown capability, low power standby mode High efficiency Thermal shutdown and current limit protection Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed frequency oscillator. A standard series of inductors optimized for use with „ Applications z Simple High-efficiency step-down regulator z Efficient pre-regulator for linear regulators z Positive to negative converter(Buck-Boost) the OCP2576 are available from several different manufacturers. This feature greatly simplifiers the design of switch-mode power supplies. Others features include a guaranteed ±4% tolerance on output within specified input voltages and output load conditions, and ±10% on the oscillator frequency. Ex...
