. Do business with integrity and operate with care. We supply discontinued spare parts, effectively supply customers, and have a lot of new stocks in stock.
.Professional service attitude, professional service team
3. Good value for money quality, with original material certificate
.Large stock inventory and management, timely stocking!
The imported spare parts sold by the company are purchased directly from foreign manufacturers and implement a flat sales model, saving customers time and costs. Our goal is that domestic users can find us when they encounter difficulties and problems in purchasing foreign spare parts. We are able to quote favorable prices and fast delivery time in a timely manner. When domestic users purchase foreign spare parts and are subject to the monopoly price of the exclusive agent, we will provide users with a comparison opportunity and provide the best solution to the customer. Due to the concentration of our orders and large order quantities, we can provide competitive prices and rapid delivery. We have long been committed to solving difficult problems for domestic users in purchasing foreign spare parts, and provide electrical and industrial control automation for our users. Comprehensive and thoughtful services such as purchase and sale of complete sets of equipment and on-site commissioning.

R: Frequency setting pin. Connect a resistor between the R pin and ground () to set the switching frequency. An internal alternative frequency
can be obtained by connecting the R pin to ground or floating: bidirectional/synchronous pin. When the R pin is left floating or set low, it is an output: when it is connected to a falling edge signal, it can also be used as an input port to synchronize the system clock:
Enable pin. When below. Enabled when the circuit stops working and is left floating
: Error amplifier output:
Error amplifier conversion node, reference voltage value:
: Analog ground, internally connected to the inductive analog ground circuit. AND and connection:
: Power ground, AND and connection
Internal. Bias voltage. This pin should be connected to a . ceramic capacitor:
: Phase terminal, connected to the external filter
Connect a . ceramic capacitor between the B pin and the pin.
.. Circuit function
3 supports medium-range current output. It can reduce the output voltage to... and its accuracy can be reached. 3 integrates high-side and an optional low-side external-gate driver. In addition, the device uses a high-performance voltage error amplifier to greatly improve performance under transient conditions, allowing flexible selection of output filter inductors and capacitors. The switching frequency is fixed at or it can be increased to reduce the size of the passive components.
The figure shows the actual application circuit of 3. The figure shows one of the cases. The output voltage is variable. By changing the resistance of the resistor R, the desired output voltage value can be obtained
/> System composition and power supply circuit
This signal processing system uses the company's multi-chip simulation radar signal processing system. The system is mainly composed of 3, 3 and 3. Used in the past and. Based on experience and after various design considerations, a type 3 converter is used. As can be seen from the table, type 3 can output voltages of 3.,. and. The clock used in the system is approximately . per instruction cycle. According to the working conditions of the model, when the temperature is ℃ and the clock (is), the typical value of the supply current is (.), and the supply current is less than. The rated output voltage of 3 is. Therefore, the design of this system is reasonable .
r has 3 power supplies, among which digital. (_) is / power supply digital. It supplies analog power to the core. (_) Internal phase-locked loop and frequency multiplier circuit power supply. The system will provide power from the host, and after 3 The voltage of . and . The digital power of each chip is supplied by 3. The internal module is solved by the same (+.) after filtering network. The power of each chip is directly provided by the host through 3 Get. Unified supply, and at the same time provide the (+.) voltage of (.3). Among them, _(+3.3) uses the +3.3 voltage of the 3 output to supply power. The power supply circuit block diagram of this system is shown in the figure. Figure 3 shows Single core power supply circuit block diagram and peripheral circuit configuration.
