Quick Detail:
BiCMOS CURRENT MODE PWM CONTROLLERS
Description:
The TC38C43 is a current mode BiCMOS PWM control IC. With a low 1.0 mA supply current along with high drive current (0.7A peak) it provides a low cost solution for a PWM that operates to 500 kHz and directly drives MOSFETs up to HEX 3 size. Performance of the oscillator and current sense amplifier have been greatly improved over previous bipolar versions. Voltage and temperature stability have been improved by a factor of 3. Noise immunity (PSRR) has also been improved.
The TC38C43 is pin compatible with the earlier bipolar version so that designers can easily update older designs.
Improvements have been added, though. For example, clock ramp reset current is specified at 2.5mA (±10%) for accurate dead time control. A few component values must be changed (RT & CT) to use the TC38C43 in existing bipolar designs.
The 14-pin DIP and 16-pin SOIC versions have separate and internally isolated grounds, and are rated for higher output current (1.2A). These separate grounds allow for‘bootstrap’ operation of the PWM to further improve efficiency
Applications:
■ Low Power BiCMOS Design
■ Tough CMOSTM Construction
■ Low Supply Current ............. 1.0mA Typ @ 100kHz
■ Wide Supply Voltage Operation .............. 8V to 15V
■ Latch-Up Immunity ................... 500mA on Outputs
■ Input Will Withstand Negative Inputs to – 5 Volts
■ High Output Drive .................................... 0.7A Peak
(1.2A on 14-Pin and 16-Pin Versions)
■ 2 kV ESD Protection
■ Current Mode Control
■ Fast Rise/Fall Time (Max) ........... 60nsec @ 1000pF
■ High Frequency Operation ..........................500kHz
■ Clock Ramp Reset Current ................. 2.5mA ±10%
■ Low Propagation Delay Current Amp to Output ............................................ 140nsec Typ.
■ Pin Compatible with UC3843
