P1595 data sheet

200KHZ, 1.5A PWM buck DC/DC converter


describe


UTC P1595 is a monolithic integrated circuit for
Using buck DC/DC converter, 1.5A load can be driven.
No additional transistors are needed.

Internal compensation makes the feedback control have good performance.
Line and load adjustment without external design. external
The shutdown function can be controlled by logic level, and then enter.
Standby mode.
UTC P1595 has a guaranteed tolerance of +3%.
Specify the input voltage and the output voltage under the output load.
Situation. Thermal shutdown protection is designed to prevent excessive
Temperature operation is damaged and current limiting protection is
Prevent overcurrent operation of the output switch. change over
If the current limiting function occurs and the feedback voltage (VFB) drops below 0.5V, the frequency will decrease. UTC P1595 operates at a switching frequency of 200kHz, so it allows the use of smaller filter components.
