A7235
Key Features
- Input voltage : 3.6V to 20V with PWM control. These devises include a reference
- Output voltage : 0.8V to VCC voltage source, oscillation circuit, error amplifier,
- Duty ratio : 0% to 100% PWM control internal PMOS and etc.
- A7235 provides low-ripple power, high efficiency and
- external transient characteristics. The PWM control circuit is able to the duty ratio linearly from 0 up to 100%. The converter is build out soft start function that prevents overshoot and inrush current at startup. An *
- Oscillation frequency is 300KHz Current limit, Short Circuit Protect (SCP) and Thermal Shutdown protection Built-in internal SW P-channel MOS Available in SOP8 Package over current protect function and short circuit protect APPLICATION function are built inside, and when OCP or SCP happens, the operation frequency will be reduced. Also, an internal compensation block is built in to minimum external component count. With the addition of an internal P-channel Power MOS, a coil, capacitors, and a diode connected externally, these ICs can function as step-down switching * * * * *
- Portable DVD Players Car Application Telecom/Networking Equipment Set Top Boxes USB 3.0 device LCD TV regulators. They serve as ideal power supply units for portable devices when coupled with the SOP8 TYPICAL APPLICATION package, providing such outstanding features as low current consumption. Since this converter can accommodate an input voltage up to 20V, it is also suitable for the operation via an AC adapter. The A7235 is available in SOP8 package.
