| Voltage References |
Typically used in transformer secondary side regulation, voltage references provide a stable voltage or current reference over a wide range of operating conditions. We offer 2.5V and 1.24V internal voltage references with tolerances of 0.25%, 0.5%, 1% and 2%. Adjustable voltage reference can also be configured with use of external components. As for voltage regulators, we offer low dropout and adjustable versions for design flexibility.

| Micropower Voltage References |
Similar to voltage references, Micropower Voltage Reference has lower turn-on current (10uA typ for AS1004-1.2 and 20uA typ for AS1004-2.5. It has greater accuracy at +/- 4mV (0.3% tolerance) and +/- 20mV (0.8% tolerance). These are guaranteed for operation up to 20mA and has bery low dynamic impedance.

 Green Mode PWM Controllers |
Green Mode PWM Controllers are more energy saving compared to regular PWM controllers. The high output current drive capability of 1A combined with low start-up current (50uA typical), low operating current (6mA) and low standby power (0.5W) make it an ideal PWM Controller where high efficiency is required.
