... VDD 2 +VIN Pre-regulator/Startup General Description The Supertex HV9112 is a BiCMOS/DMOS single-output, pulse width modulator IC intended for use in high-speed, high-efficiency switch mode power supplies. It provides all the functions necessary to implement a single-switch current mode PWM, in any topology, with a minimum of external parts. Because the HV9112 utilizes Supertex’s proprietary BiCMOS/ ...

... OSC OUT is required to set the oscillator frequency (see graph). One major difference exists between the Supertex HV9112 and competitive 9112s. On the Supertex part, the oscillator is shut off when a shutoff command is received. This saves about 150µA of quiescent current, which aids in the construction of power supplies that meet CCITT specifi ...
