AH599L is an ultra-small packaged small-sized SOT23-6 packaged step-down chip AH599L emergency light bar step-down chip 36V-43V to 3.3V 100MA 38V to 5V 400MA 600MA SOT23-6 small packaged step-down chip 1.6KHZ high frequency step-down chip 50V step-down IC AH599L replaces the 60V step-down chip AH599L on the market instead of the 88104 chip instead of the 9459 chip, which can completely replace the emergency light scheme.Shenzhen Zhenbang Micro-Technology Co., Ltd. newly supplies 60V buck 5V-12V buck chip POE power water meter products. Welcome to inquire. This is a super-hot chip that solves the board space size requirements for customers. AH599L is a synchronous buck chip with high efficiency, small size and low cost. It is the first choice of customers. Your choice is the biggest support of our company. AH599L can replace TD1466 and MP2459 AH599L 12V-60V for manual output. The direct 5V voltage and current can reach 600MA, and the input voltage is 24V-40V. The output voltage of 5V 400MA less than 20uA AH599L allows the use of smaller external components, with high efficiency and high frequency, while still having low output voltage ripple. The soft start function is realized through the enabling terminal pin, and the user can be specified by connecting an external RC circuit. AH599L is a switching mode conversion chip with built-in MOS single chip for synchronous voltage reduction. It is small in size and can realize the maximum peak output current of 600MA. The input voltage is 4.5-60 V, which has good load and line regulation ability. The current mode operation provides fast transient response and simple loop. AH599L is an ultra-stable one with the functions of current limiting and thermal shutdown on a weekly basis. The peripheral circuit is simple and can be completed with only a few components. Make the chip more powerful and stable, with a built-in 0.7 ohm power MOS tube, the efficiency can be as high as 91%<1μA shutdown power consumption, the frequency is fixed at 480KHz, and the thermal shutdown cycle is every Monday. 36-42V to 3.3V/100-200mA 12-48V to 5V/300-500mAAH599L is a step-down switching regulator with integrated power MOSFET. A current mode control mode is adopted to achieve fast response and improve the stability of the loop. A wide range of input voltage (4.5V to 60V) provides a high-efficiency output of 0.5A current, which can realize various applications of step-down power conversion under the input condition of mobile environment. The shutdown static current of 0.1uA is suitable for battery-powered applications. Fault protection includes cycle-by-cycle current limiting protection and thermal shutdown protection. Circuit periphery is simple.* 0.5A peak output current * 4.5V to 60V wide working voltage range * 1ω internal power MOSFET * 480KHz fixed switching frequency * ceramic output capacitor voltage stabilization * cycle-by-cycle overcurrent protection * thermal shutdown protection * >90% efficiency * output adjustable from +0.81V to 0.95Vin * low shutdown mode current: < 1μ A.AH599L this chip adopts standard SOT23-6 lead-free package and has been supplied in largeWX: Wv-88788 quantities.
