一,产品概述(General Description)
The JTMA7176 consists of two independent 1.5MHz constant frequency, current mode, and PWM step-down converters. Each converter integrates a main switch with a synchronous rectifier for high efficiency without an external Schottky diode. The JTMA7176 is ideal for powering portable equipment that runs from a single cell Lithium Ion (Li+) battery. Each converter can supply 1A of load
current from a 2.7V to 5.5V input voltage. The output volt age can be regulated as low as 0.6V. The JTMA7176 can also run at 100% duty cycle for low dropout applications.
