P1785 LINEAR INTEGRATED CIRCUIT
PWM CONTROL 2A STEP-DOWN CONVERTER

DESCRIPTION

UTC P1785 consists of 2A step-down switching regulator control which includes a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc with PWM.
UTC P1785 can provide low-ripple power, high efficiency, and excellent transient characteristics and an enable function, an over current protect function and a short circuit protect function are built inside, so the operation frequency will be reduced from 300KHz to 30KHz when OCP or SCP happens. And the PWM control circuit can vary the duty ratio linearly from 100 down to 0%. This converter also includes an error amplifier circuit as well as a soft-start circuit that prevents overshoot at startup. Also, to minimum external component count an internal compensation block is built in.
These ICs can work as step-down switching regulators with the addition of an internal P-channel Power MOS, a coil, capacitors, and a diode connected externally. They provide such outstanding features: low current consumption. It is also suitable for the operation via an AC adapter because this converter can accommodate an input voltage up to 23V.

FEATURES
  • Soft-start, Current Limit, Enable function
  • Thermal Shutdown function
  • Built-in internal SW P-channel MOS
  • Input voltage: 3.6V to 23V.
  • Output voltage: 0.8V to VCC.
  • Duty ratio: 0% to 100% PWM control
  • Oscillation frequency: 300KHz typ.

P1785 線性集成電路
PWM 控制 2A 降壓轉換器

描述

UTC P1785由2A降壓開關穩壓控制組成,包括參考電壓源、振盪電路、誤差放大器、內部PMOS等帶PWM。
UTC P1785 可提供低紋波功率、高效率和出色的瞬態特性,並且內置使能功能、過流保護功能和短路保護功能,因此在 OCP 或SCP 發生。 PWM 控制電路可以將佔空比從 100 線性變化到 0%。該轉換器還包括一個誤差放大器電路以及一個防止啟動時過衝的軟啟動電路。此外,為了最大限度地減少外部組件數量,內置了一個內部補償塊。
這些 IC 可以用作降壓開關穩壓器,並增加了一個內部 P 溝道功率 MOS、一個線圈、電容器和一個外部連接的二極管。它們提供瞭如此出色的特性:低電流消耗。它也適用於通過交流適配器進行操作,因為該轉換器可以適應高達 23V 的輸入電壓。
