JTMA7300 is a 2A synchronous buck converter with integrated

一,产品概述(General Description)
JTMA7300 is a 2A synchronous buck converter with integrated power MOSFETs.
The JTMA7300 design with a current-mode control scheme, can convert wide input
voltage of 4.5V to 24V to the output voltage adjustable from 0.925V to 20V to provide excellent output voltage regulation.
The JTMA7300 is equipped with an automatic PFM/PWM mode operation. At light
load, the IC operates in the PFM mode to reduce the switching losses. At heavy load, the
IC works in PWM.
The JTMA7300 is also equipped with Power-on-reset,soft- start, soft-stop, and whole protections (under-voltage, over-temperature, and current-limit) into a single package.
This device, available SOP-8, provides a very compact system solution external components and PCB area.
