AP1510 詳細介紹

AP1510 consists of step-down switching regulator with PWM control. The AP1510 include a reference voltage source, oscillation circuit, error amplifier and internal PMOS. AP1510 provides low-ripple power, high efficiency and excellent transient characteristics. AP1510 PWM control circuit is able to vary the duty ratio linearly from 0 up to 100%. The AP1510 also contains an error amplifier circuit. An enable function, an over current protection and a short circuit protection are built inside, when OCP or SCP happens, the operation frequency will be reduced from 300kHz to 30kHz. 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, AP1510 can function as step-down switching regulators. They serve as ideal power supply units for portable devices when coupled with the SOP-8L package, providing such outstanding features as low current consumption. Since AP1510 can accommodate an input voltage up to 23V, it is also suitable for the operation via an AC adapter.
