DESCRIPTION

The TJ1509A series are monolithic IC designed for a step-down DC/DC converter, and own the ability of

driving a 2A load without additional transistor component. Due to reducing the number of external

component, the board space can be saved easily. The external shutdown function can be controlled by

logic level and then come into standby mode.

The internal compensation makes feedback control have good line and load regulation without external

design. Regarding protected function, thermal shutdown is to prevent over temperature operating from

damage, and current limit is against over current operating of the output switch. If current limit function

occurred and VFB is down to 0.5V below, the switching frequency will be reduced.

The TJ1509A series operates at a switching frequency of 150KHz thus allowing smaller sized filter

components than what would be needed with lower frequency switching regulators. Other features

include a guaranteed +4% tolerance on output voltage under specified input voltage and output load

conditions, and +15% on the oscillator frequency.

The output version included fixed 3.3V, 5V, 12V, and an adjustable type.

The packages are available in a standard 8-lead SOP-8 package.
