Description
The MC34166, MC33166 series are high performance fixed frequency power switching regulators that contain the primary functions required for dc-dc converters. This series was specifically designed to be incorporated in buck, boost and inverting applications with a minimum number of external components and can also be used cost effectively in step-up applications. These Buck Boost Inverting Switching Regulators consist of an internal temperature compensated reference, fixed frequency oscillator with on-chip timing components, latching pulse width modulator for single pulse metering, high gain error amplifier and a high current output switch. Protective features consist of cycle-by-cycle current limiting, undervoltage lockout, and thermal shutdown. Also included is a low power standby mode that reduces power supply current to 36 mA.

The MC34166, MC33166 series are high performance fixed frequency power switching regulators that contain the primary functions required for dc-to-dc converters. This series was specifically designed to be incorporated in step-down and voltage-inverting configurations with a minimum number of external components and can also be used cost effectively in step-up applications.
These devices consist of an internal temperature compensated reference, fixed frequency oscillator with on-chip timing components, latching pulse width modulator for single pulse metering, high gain error amplifier, and a high current output switch.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
1. This device series contains ESD protection and exceeds the following tests:ELECTRICAL CHARACTERISTICS (VCC 12 V, for typical values = +25°C, for min/max values TA is the operating ambient temperature range that applies [Notes 3, 4], unless otherwise noted.)
Output Voltage Source Saturation (VCC 7.5 V, ISource 3.0 A)3. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
