STK7561A Datasheet (Sanyo Semicon Device) - Chopper Type Parallel 2-Output Voltage Regulators

STK7561A, Chopper Type Parallel 2-Output Voltage Regulators

of Operation of Internal Blocks [OSC] External excitation type OSC circuit where the CMOS NAND gate-used ring OSC is formed by the 2-stage NAND circuit, delivering basic pulses.

This circuit provides pulse width modulation where the frequency is constant and the duty only varies.

[PWM] Pulse width

STK7561A Features
