General Description
The Supertex HV9110 through HV9113 are a series of BiCMOS/ DMOS single-output, pulse width modulator ICs intended for use in high-speed high-efficiency switchmode power supplies. They provide all the functions necessary to implement a single-switch current-mode PWM, in any topology, with a minimum of external parts. Because they utilize Supertex’s proprietary BiCMOS/DMOS technology, they require less than one tenth of the operating power of conventional bipolar PWM ICs, and can operate at more than twice their switching frequency. Dynamic range for regulation is also increased, to approximately 8 times that of similar bipolar parts. They start directly from any DC input voltages between 10 and 120VDC, requiring no external power resistor. The output stage is push-pull CMOS and thus requires no clamping diodes for protection, even when significant lead length exists between the output and the external MOSFET. The clock frequency is set with a single external resistor. Accessory functions are included to permit fast remote shutdown (latching or nonlatching) and undervoltage shutdown. For similar ICs intended to operate directly from up to 450VDC input, please consult the data sheet for the HV9120/9123.
